Last entries of failed logs below:It looks like Olof's boot bot came back after a time without running any tests, and found a regression on Arndale when running with CONFIG_SMP disabled. cubie2 did not run into the same problem.
The backtrace looks a bit suspicous. I can see __switch_to() calling the notifiers, which would be vfp_notifier_block and contextidr_notifier_block on both those machines.
I was doing a trial run with just a few boards, it's a bit premature to claim it's back. I didn't mean for the email to go out.
Looks like kernelci doesn't cover CONFIG_SMP=n boots, so I guess this might be a new issue.
I haven't automated the new setup yet, so this was a one-off. I'll bisect it over the weekend.
