I was doing an 'emerge -e @world' in Gentoo Linux and probably building a kernel in another shell. Noticed it only in the logs on the next day so I can't tell exactly which command triggered the issue. But I will pay closer attention from now on. > If this is happening with only the recent kernel and working with a previous > kernel, do you happen to know the previous kernel version. > In which case, is there a possibility of doing a git bisect? I think I have not seen this in v6.13, certainly not in v6.12. As I get this only from time to time bisecting will be hard. For that purpose I have yet to find a way to trigger it more reliably. But I'll take your hints and try! Regards, Erhard
