Hi, I can definitely help you with this issue. Nine times out of ten, random shutdowns like this point to ACPI or firmware conflicts. I will start by analyzing the BMC/IPMI/SEL logs to catch any hardware events leading up to the shutdowns. Also, I'll audit the kernel ring buffer to spot any anomalies. I can deliver the initial analysis for the first BRIX unit in 10 days. Is the scope fully defined, or still flexible?

@MuhammadUzair16

Hi I am a Linux/infrastructure engineer with over 16 years of experience debugging production systems where the fault sits between Linux, firmware, power management, and hardware behavior. This BRIX issue sounds like the right kind of investigation: Debian is likely only seeing the effect, while the actual trigger may be ACPI, BIOS/firmware, thermal or power events, watchdog behavior, or a hardware-specific kernel interaction. I would start with one affected unit, compare it against healthy fleet behavior, collect journald/dmesg/kernel ring buffer data, firmware and BIOS settings, power/thermal history, ACPI events, watchdog configuration, and hardware event logs where available. Once the likely cause is isolated, I can document the remediation and convert any repeatable OS-side changes into Ansible so the fix can be rolled out cleanly across all 13 machines. A few useful details before starting: do you have remote console access to the BRIX units, are BIOS/firmware versions consistent across them, and do the shutdowns correlate with load, temperature, idle time, or site power conditions? Please contact me to discuss details.

Hi, I have 8+ years of experience in Linux system administration, infrastructure engineering, and production troubleshooting, with hands-on expertise in Debian/Ubuntu, kernel-level debugging, hardware diagnostics, and Ansible-managed environments. Your issue clearly points toward a hardware/firmware interaction rather than an OS-level problem, and my approach will focus on isolating the root cause methodically instead of applying temporary fixes. My investigation will include: Deep analysis of kernel logs (dmesg, journald, kdump if required) ACPI, power management, BIOS/UEFI, and firmware validation Hardware event log review (IPMI/BMC/SEL where available) Thermal, PSU, watchdog, and kernel panic investigation Comparison between affected BRIX units and healthy systems Review of Debian 12 kernel versions, drivers, and firmware packages Audit of Ansible configurations to identify any hardware-specific differences Deliverables will include a detailed root cause analysis, documented remediation steps, monitoring recommendations, and any required Ansible playbook updates for deployment across all affected systems. I believe starting with a single BRIX unit is the right approach to reproduce and isolate the issue before rolling out a verified fix fleet-wide. I’m available to start immediately and can work closely with your team until the problem is fully resolved.

@VanizG

hello, you need to identify the root cause of random shutdowns affecting only your brix mini-pcs running debian 12. since the issue appears to occur below the operating system, the investigation will focus on firmware, acpi, kernel events, hardware logs, power management, and ansible-managed configuration differences before applying a reliable fix across all affected machines. i have experience with linux system administration, debian/ubuntu servers, kernel-level troubleshooting, acpi and power management debugging, ansible automation, hardware diagnostics, and production infrastructure support. i can investigate one affected system first, analyze kernel and hardware logs, review bios and firmware settings, compare configurations with healthy servers, document the findings, recommend monitoring improvements, and prepare any required ansible updates for the remaining systems. best regards, dharam

@AlexTheron1

Hi, I can surely assist you in debugging the random shutdowns on your 13 BRIX machines running Debian 12. I will conduct a thorough root cause analysis, focusing on ACPI, power management, and hardware-firmware interactions. Deliverables include a detailed report on the shutdown issue, documented fix instructions, and recommendations for proactive monitoring. I will also adjust any necessary Ansible playbooks. Let's start with one BRIX machine and expand as needed. Timeline for root cause identification and fix implementation is estimated at 2-3 weeks. One question: Do you have remote access and physical access details for all 13 BRIX machines? Regards, Alex

@carlosporter

Hello, I can help identify why those 13 BRIX units are shutting down. Since standard OS logs show nothing, the issue likely sits at the firmware or hardware boundary, involving ACPI states, thermal throttling, or power delivery faults that bypass the kernel ring buffer. I have extensive experience with Debian and Ubuntu systems, including deep troubleshooting of storage, power, and kernel interactions. I also manage fleets using Ansible, so I can quickly audit your current playbooks for any conflicting power management settings once we isolate the cause. My approach involves analyzing BMC or IPMI SEL logs alongside dmesg output from a failed node to find pre-shutdown hardware events. I can test ACPI and thermal parameters on one unit to confirm the trigger, then document the fix and update your Ansible playbooks to prevent recurrence across the fleet. I can review the setup with you and map the next steps. Carlos Porter Site Reliability Engineer

⭐ Hi there ! Let's set meeting schedule for ur project more detail . A fleet issue where the same Debian 12 image fails only on BRIX hardware needs hardware specific Linux debugging not generic server admin work In a similar infra case the fix came from comparing kernel logs power settings BIOS firmware and hardware event traces across affected and healthy machines That reduced random node loss because the real cause was outside app logs For your setup I would first isolate one BRIX machine then check ACPI power management watchdog thermal throttling BIOS settings firmware revisions PSU behavior and SEL style event data if available After confirmation I would write remediation steps that can be pushed through Ansible across all 13 units Monitoring can include shutdown reason capture uptime deltas thermal alerts power state changes and journald pattern checks Do you already have timestamps from the shutdown windows across different sites Timeline : 5 days initial RCA Total Budget : 8 USD hourly

@ASirbescu

Hello, Your issue strongly suggests a firmware, ACPI, power delivery, or hardware event occurring below the operating system. I'll perform a systematic investigation by correlating kernel logs, SEL/IPMI events, BIOS/firmware versions, power settings, and hardware configurations across all 13 BRIX units to isolate the common trigger. Once identified, I'll provide a documented root cause, a repeatable fix, monitoring recommendations, and any required Ansible updates to roll the solution out consistently across your fleet. A couple of questions: Are all 13 BRIX units running the same BIOS/firmware version and identical hardware revision? Do the shutdowns happen under specific workloads, or are they completely random even while idle?

@luispablor

Hi there, When a machine dies without one word in the logs, it is not being quiet on purpose. It is telling you the shutdown happened below where the OS can watch. Thirteen BRIX dropping across sites while forty seven other boxes stay up is not a software ghost, it is hardware whispering under the kernel, the layer I like working at. The BRIX are consumer small form factor boards, not servers, so clean empty logs before each drop is the clue. A thermal trip, a brownout, or a firmware level ACPI event leaves no trail, the plug is pulled before the kernel can flush to disk. I have chased this exact shape before, small boxes rebooting with empty logs that everyone blamed on the kernel. I put capture in front of the problem first, pstore and ramoops for the dying breath, netconsole to stream it off the box, plus continuous temperature and voltage sampling. The graph confessed within days, a thermal trip on units with aged paste and choked fans, mechanical and firmware side, not code. Your BRIX get the same treatment. Start with one unit, record the next shutdown instead of losing it, confirm root cause, then fold the monitoring into your Ansible so the fix holds across all thirteen. One real question. Most BRIX ship without a true BMC, so out of band SEL is often missing here. Do these expose any lights out management, or is it OS plus a serial path? That shapes how I instrument the first box. Happy to dig into the kernel and firmware detail right here whenever. Regards
