Subject: next-20080725: System hangs while suspending to disk

I tried to get some console output, so i tried "test" instead of
plattform and got an oops in native_cpu_up().

When i do "echo 0 > /sys/devices/system/cpu/cpu1/online" and
"echo 1 > /sys/devices/system/cpu/cpu1/online" again, i get the
same Oops report (as compared to a "test run with state disk")

http://kerneloops.org/guilty.php?guilty=native_cpu_up&version=2.6.26-release&start=1736704&end=1769471&class=oops

What is wrong here?

You may want to ping cpu hotplug people.

Problem is already solved. See commit 583323b9d2f624884a8c9563fb5a4d795f39ab07

Vegard Nossum did take care of the problem. See also thread "-git: BUG: unable
to handle kernel paging request at c0100248 [CPU hotplug]" from 27.07.

Suspending to disk works fine now.
