At a guess I'd say that the hrtimer data structures got wrecked.
If possible, please see if we fixed it in 2.6.27-rc8. If so, there
might be a patch we need to backport (although is might have been
backported into later 2.6.25.x's as well).
We have 10 equal server what do Trafiic Shape (tc (htb, u32, sfq) and
iptables) only. Few of them halt one times in week.
Timer settings in config:
Ok. I will try. Only one question - iTCO watchdog don't work on this
platform (but chip have it... ICH9R). How i can reboot server remotely
if it halt?
