Hi!
For some reason, Thinkpad X60 now crashes during boot. I see some
weird backtraces, and it may be bfq related... or maybe ACPI idle.
Does x86-32 work for you?
Weird thing is, 5.1.0-rc3-next-20190408 boots here (but later has
problems during resume, making it unusable, too). They may not have
100% same configs.

Can you try and revert:

and see if that helps?

Yes, I tried and yes, it helps. What are the next steps?

It seems to work... even without fingers crossed.

Thanks,
