Syslog from faillure to next reboot
Hello,
Something really bizarre happened with firefox. It seems the kernel stopped to
serve filesystem request because a hung process.
I ran de mozilla demo bananabread, exited one level and entered another and
everything stopped to work. I tried to kill the process but it has a "D" on the
status and cannot be killed.
After a while everything stopped to work. Even the reboot didn't work. I had to
unplug the machine.
Kernel logs (syslog) is attached.
It seems something was failing in the disk. It has everything there until next
reboot.
I don't know if it's a bug or not but wanted to make sure that nothing can be
done.
I did an error installing bios raid. I have to undo it but I'm a little bit
afraid of undoing without a backup.
root@...1:/var/log# dmraid -r
/dev/sdb: pdc, "pdc_bbbgggjccd", mirror, ok, 625011328 sectors, data@ 0
/dev/sda: pdc, "pdc_bbbgggjccd", mirror, ok, 625011328 sectors, data@ 0
This raid is getting me into troubles. Disk sdb is what failed.
