I have been affected by the same bug after upgrading ubuntu 20.04 LTS from kernel 5.8 to 5.11. I have a Dell Latitude 7390. Random freezes when plugged in initially, but worked on battery. After changing motherboard, random freezes even on battery... I have downgraded to kernel 5.4.0-88-generic and no freezes until now. I have tested latest daily build of ubuntu 21.10 (kernel 5.13) and kernel 5.14.11-051411, system freezes even with these recent versions. So for me it seems that all kernels > 5.8 are affected.
