I had exactly the same panic, also on a FreeBSD 7 system
with gmirror. I'm not sure if it's related, but I tell
you my story anyway ...
Apparently it was caused by a bug that caused corruption
in the file system. The bug was fixed in October, IIRC,
but the corruption remained and eventually crashed the
machine again. A forced fsck ("fsck -f -y") seems to have
fixed it for me finally.
So, my recommendation is this:
- Make sure you update to the latest sources.
- "fsck -f -y" all your filesystems in single-user mode.
Alternatively, newfs them and restore from backup.
