Some further logfile around a lockup

I tried and failed to manually lockup a kernel (tried 10 bonnie++ and
tiobench), but another one (2.6.24 with openvz patch but I believe openvz
shouldn't really matter to qla2xxx driver; you're free to disagree) locked up,
maybe there's something useful in the logs (the log drive wasn't stuck, no
OOPS).

The links seem to go down, but they most probably did not, since all other
servers went on completely fine at the time. Links seemed stayed down [and
locked up IO], but came up again after a reboot. I do not believe the links
were _really_ down at all, so this - by my guess - is the same problem.
Everything went to syslog. 

Plus I attached some proc/interrupts and ps tree and whatnot.
