Thinkpad X60: regression with 5.1-rc1 and 5.1-rc4
Subsystems (2)
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?

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

Great! I've submitted a final version of this fix patch a few minutes ago (not yet archived anywhere, sorry).
Thanks,
