:I cvsup'd and built world+kernel a few hours ago and was happy to see
:KDE working again, but I got a spontaneous reboot while trying to track
:down a segfault in a mozilla build component. I "boot -v"'ed and as
:soon as the login prompt came up I hit a panic. I'm guessing the
:backgorund fsck had something to do with it. I'll hand-copy the trace
:here; any debugging info needed while my box is stuck at the debugger,
:lemme know:
I don't have the output to show people since I was trying to reproduce but
couldnt, but i got essentially the same panic, but it came only from a
syscall to open() that called ufs_create() -> ufs_makeinode ->
ffs_valloc() -> panic.
I can try and reproduce (tho, mine occured when just running cscope) and
get a dump.
Cheers,
Andrew
