Hi!
Are there any recent changes in cpu hotplug? I have suspend (random)
problems, nosmp seems to fix it, and last messages in the "it hangs"
case are from cpu hotplug...

I also have problems like this, investigating.
Please check if that started to trigger after the scheduler changes (you'd
need to go to commit b47711bfbcd4eb77ca61ef0162487b20e023ae55 IIRC).
Thanks,
Rafael

Hi Pavel,
Can you send along your cpuinfo?

Ah, ok. This one is a C2D, correct? The only reason I asked is that
someone was reporting an s2ram problem on P4s on some of that
root-domain logic I submitted a little while ago (and was merged in
.25), whereas C2D seemed fine. That doesn't mean anything here,
really. The problem could still be my code, or it might be unrelated.
I was just wondering if you also had a P4 on the troubled systems.
So is your problem on suspend or resume? (or both?) (I know you
mentioned it was random problems, but I wasn't sure if you could qualify
that further)
Any info you can provide will be appreciated.

I don't know what "C2D" means... core2duo? Yes, this is core2duo.

It dies at suspend, always in same place, but not always.
OTOH last few suspends worked for me, not sure what changed...
