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.
