This looks like some sort of list corruption. If you are able to reproduce this, can you add "thunderbolt.dyndbg" to the kernel command line and attach full dmesg when this happens? Thanks for the tip, I'm running with thunderbolt.dyndbg now. It might take a few days for this corruption to occur again, will post updates then. Surprisingly, I haven't been able to make the system hang recently. Also updated to 5.15.7 and 5.15.10. Continuing to keep an eye out for a while longer. |
