Subject: PROBLEM: BUG: unable to handle kernel paging request at ffff81013a612000
Hi,
Please CC me with any replies as I'm not subscribed to the list.
I'm running a vanilla 2.6.25.4 kernel.
I apparently hit a bug in the kernel.
When the problem starts my system becomes very unstable, many programs
crash others I can barely shut down correctly and a reboot fails.
I've hit the problem once trying to do "echo disk > /sys/power/state"
and another time while writing do the disk inside a vmware guest.
And a couple of times it happened randomly, e.g. while converting some
files to mp3's and writing them to a usb device.
(More details about my system at the end of the mail)
dmesg output:
