Comment 7 for bug 1931301

It might be caused by the patch https://github.com/torvalds/linux/commit/a4dcfbc4ee2218abd567d81d795082d8d4afcdf6 which is the only difference between 20.10 and 21.04 kernel.

I build a test hirsute kernel in https://people.canonical.com/~mschiu77/lp1931301/v1/, could you install and check if the problem still persists? Please also provide me the full dmesg log based on this kernel. Thanks.
