Hello,
I am encountering kernel oops shortly after boot (10-15 minutes)
when running the latest kernel in the 5.10.y series. Git bisect
suggests that c21b4002214c is the commit that introduced the issue.
The machine has a AMD Ryzen 7 4800H processor and a Navi 10 graphics
card. I am happy to provide more information if needed. An excerpt of
syslog containing the panic is included below.
Thank you,
Ben
