I own a Huawei laptop, model KPL-W00D with Ryzen 2500U and it suffer this s= ame bug. I cannot compile a kernel so, after installing Devuan testing, I installed = also the generic kernel located here: https://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2021-03-15/amd64/ that is a 5.12.0 RC3 and it includes the upstream patch for this bug. The patch works but only on cold boots, after a simple reboot the bug turns back again. Maybe it's only a hardware problem, maybe a distro fault or misconfiguratio= n, I don't know, but I felt compelled to report this. If needed I can give more detailed informations. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
