Dear maintainers,
I might be hitting the same problem, but I can see the kernel panic
message:
First a couple of lines saying:
"AMD-Vi: Completion-Wait loop timed out"
then:
"Kernel panic - not syncing: timer does't work through
Interrupt-remapped IO-APIC"
I was experiencing this also with the 5.14.0-trunk kernel and the 5.13
before from experimental.
I updated the Lenovo BIOS to the current version but the problem
persists. Also, booting with "amd_iommu=off" did not help.
Do you need more information? Unfortunately this did not make it to the
system logs.
kind regards,
Jens-Michael
