I'm seeing this problem on 2.6.11-1.14_FC3smp, a part of dmesg is
supplied below. (these messages have flooded the buffer).
Kernel was updated from kernel-smp-2.6.9-1.667 yesterday, and no
similar messages was in dmesg at that time after 8 days uptime.

Fedora Core 3 w/latest updates atm
Running Mysql, exim, http + perl, clamav, spamassasin, courier.

Tyan motherboard, dual AMD 246, 4x512MB ram (one on each bus),
two 3ware 9xx, dual broadcom nic. (lspci output below)

I have not tried the testing kernel you suggested, but will see what
time will allow today. We already have a scheduled reboot on it so
maybe I'll just sneak in a kernel update again.

More info available on request.
