Hello,
Xorg always restarts again and again after the the PowerPC updates 5.13-1 [1] on my FSL P5040 Cyrus+
board (A-EON AmigaOne X5000) [2]. Xorg doesn't start anymore in a virtual e5500 QEMU machine [3].
I bisected today [4].
Result: powerpc/signal32: Convert do_setcontext[_tm]() to user access block
(887f3ceb51cd34109ac17bfc98695162e299e657) [5] is the first bad commit.
Please find attached the kernel config.
Please check the first bad commit.
I'm not sure you can conclude anything here. There is a problem in that commit, but it is fixed by
525642624783 ("powerpc/signal32: Fix erroneous SIGSEGV on RT signal return") which is the last
commit of powerpc-5.13-1.
So any bisect from there will for sure point to 887f3ceb51cd ("powerpc/signal32: Convert
do_setcontext[_tm]() to user access block") but that's unconclusive. If the problem is still there
at the HEAD of powerpc-5.13-1, the problem is likely somewhere else.
I think you need to do the bisect again with a cherry-pick of 525642624783 at
each step.
Thanks
Christophe
