This page documents all system freezes, hard lockups, and kernel panics, including the analysis of logs captured post-recovery.
| Field | Details |
|---|---|
| Type | Hard Lockup (Host) |
| Trigger | Magic SysRq (REISUB) |
| Approx Time | 14:12:00 |
| Last Journal Entry | kernel: vfio-pci 0000:00:02.1: reset done |
1. iGPU VF Reset: The crash occurred immediately after the VM attempted to enable and reset the iGPU VF (00:02.1). The host logs show VF1 FLR (Function Level Reset) followed by reset done, but the journal stopped abruptly after this.
2. Process Noise: The python3 process (Gemini Voice) was in a high-frequency loop logging “Error: API Key not found” every 5 seconds. This contributed to high I/O and CPU context switching overhead during the sensitive VF reset period.
3. Service Failure: max-performance.service had a fatal configuration error, potentially leaving the CPU/GPU in an inconsistent power state before the VF was engaged.
* Disabled Gemini Voice: Persistent removal of the service to eliminate the high-frequency error loop. * Fixed Performance Service: Refactored into a standalone script to ensure stable power states on boot. * Btrfs Check: Verified Btrfs integrity after the unclean shutdown (renamed/replaced corrupted journal).
System stabilized after post-reboot optimizations and removal of the failing voice assistant process. No further hangs detected during VM XML updates.
