>Description:
I've been plagued by this panic for quite a while now on my internet gateway/proxy/firewall machine. It's started on version 2.2.5. Recent upgrade to -STABLE didn't help a bit. System crashes only at day time, when my local users are actively browsing the Net.
I found two old unresolved and closed, but suspiciosly similar PRs: kern/216 and kern/7288. Mine system has the same SCSI adapter as theirs: NCR 53c815.
Dmesg and kgdb output follows.

>How-To-Repeat:
I don't think it's possible to reproduce exactly my setup and network environment. System crashes at random time about once a day. Vmcore files are avaliable upon request.
>Fix:
Not known. Many thanks in advance to anyone who can spend some time investigating this problem.
