Package: linux-image-6.12.107+deb13-amd64 Version: 6.12.107-1 Severity: normal
Dear Maintainer, I am experiencing an intermittent issue on Debian Trixie where the onboard Intel Raptor Lake High Definition Audio Controller (ASRock Device 6899) becomes completely unavailable after a system reboot (occurring roughly once or twice a month). The issue seems to manifest after heavy audio/video workloads in the previous session (e.g., using Google Chrome, Ardour, or Audacious). When the failure state occurs, a standard software reboot or cold reboot does not restore the audio hardware. The only working recovery sequence is to stop Pipewire/Wireplumber, shut down the PC, unplug the AC power cord, and hold the case power button for 30 seconds to drain the motherboard capacitors before booting back in. TECHNICAL ANALYSIS: During the failure state, the device remains visible on the PCI bus, and `dmesg` shows a perfectly clean driver initialisation sequence with no explicit errors or timeouts. However, checking `lspci -vvv` reveals that the hardware becomes persistently trapped in the D3 power-saving state, and the `NoSoftRst+` flag prevents the kernel driver from forcing a recovery without a physical power drain.
