Description:
After updating the above packages I receive a reproducible kernel panic. RIP is at mt76_dma_add_buf.constprop.[some offset]. I use a Lenovo P14s Gen2 (AMD) platform. The kernel panic does not occur if I do not load amd-ucode.img during boot. When the panic is triggered, my kernel command line looks like this: initrd=\amd-ucode.img initrd=\initramfs-linux.img cryptdevice=/dev/nvme0n1p2:cryptroot root=/dev/VolGroup0/root rw add_efi_memmap With this command line, no panic occurs: initrd=\initramfs-linux.img cryptdevice=/dev/nvme0n1p2:cryptroot root=/dev/VolGroup0/root rw add_efi_memmap Additional info: * package version(s) linux: 5.16.arch1-1 amd-ucode: 20211216.f682ecb-1 * config and/or log files etc. A 'screen picture' can be found in the attachment. I think it's quite readable, please tell me if you need better quality. No trace of the panic in journalctl -b-1. * no upstream bugs known to me so far * lspci: 00:00.0 Host bridge: Advanced Micro Devices, Inc.
