So that one didn't help. I've also been bisecting the trace but have not finished it yet as the last half dozen builds produced non-bootable kernels. Anyway, I will continue it soon(ish) when I have a bit more free time. --Ilkka On Tue, Jun 18, 2024 at 5:52=E2=80=AFPM Steven Rostedt wrote: > > On Thu, 13 Jun 2024 10:32:24 +0300 > Ilkka Naulap=C3=A4=C3=A4 wrote: > > > ok, so if you don't have any idea where this bug is after those debug > > patches, I'll try to find some time to bisect it as a last resort. > > Stay tuned. > > FYI, > > I just debugged a strange crash that was caused by my config having > something leftover from your config.
