Package: linux-image-3.2.0-4-686-pae Version: 3.2.60-1+deb7u3
I've just upgrade a server as in subject from squeeze to wheezy: the
server run squeeze for years, without troubles or unexpected
reboots/failures.
Upgrade went well, but after rebooting to the new kernel system became
instable and hang ''randomly'' after some hours or some days (2-3 max).
Clearly, the server is in production and on a remote location. ;(
I've managed to reboot it on the old 2.6 kernel, and the server is now
stable as before, so i suppose is a kernel trouble.
Some sparse info:
1) server hang because /var ''desappear''; i've managed to go on
console, and what i see is only some gereric error like:
task XXXX:YYYY blocked for more than 120 seconds.
"echo 0 > /proc/sgs/kernel/hung_task_timeout_secs" disables this
message.
no PANIC or something like that.
2) /var is a XFS filesystem.
3) because my log is on /var, i've no more info to provide...
Attached the boot log of the two kernels; the only strage thing i note
is:
Aug 12 13:59:03 rita kernel: [ 1.231468] HP CISS Driver (v 3.6.26)
Aug 12 13:59:03 rita kernel: [ 1.231583] cciss 0000:09:02.0: PCI IRQ 72 ->
rerouted to legacy IRQ 16
Aug 12 13:59:03 rita kernel: [ 1.231665] cciss 0000:09:02.0: Controller
reports max supported commands of 0, an obvious lie. Using 16. Ensure that
firmware is up to date.
But i don't know if is related.
Say me if more info are needed. Thanks.
