PERC3/Di crashes, even with kernel 2.4.25 and aacraid 1.1.5

Dell 2650 BIOS A15
PERC3/Di firmware 3170
ext3 filesystem

It crashed less than 2 days after rebooting, which is less uptime than with RedHat kernel 2.4.18-14smp

See below for contents of log.

cheers,

Crashed again :(

It seems that the problem occurs when the cron daily jobs run. It looks like the system survived the cron daily job on April 11, but not April 12.

Its only since i upgraded to kernel 2.4.25 and aacraid 1.1.5 that i've started to get anything like this in the logs.

# ls /etc/cron.daily/

Any ideas what I should try next?

thanks,
