A week or so ago, I reported a kernel panic in the uvm subsystem, which
I'd never seen before, and apparently noone else has seen it, either.

Well, today I just had another crash, this time in ffs_newvnode(). The
traceback (manually transcribed) is:
vpanic + 0x140
snprintf
ffs_newvnode + 0x402
vcache_new + 0x9e
ufs_make_inode + 0x38
ufs_create + 0x52
VOP_CREATE + 0x3d
vn_open + 0x351
do_open + 0x112
do_sys_openat + 0x68
sys_open + 0x24
syscall + 0x15b
Theonly thing that was going on at that time was a cvs update - I had
just sent an Email seconds earlier.
A couple of items to note:
1. This is with WAPBL, QUOTA, and QUOTA2 all enabled. All file systems
have wapbl enabled, but there are no quotas being enforced.
2. Both ffs and wapbl are modular, and loaded at boot time via /boot.cfg
FWIW, it seems that my USB keyboard is currently non-functional in gdb.
I think this is a consequence of the recent nick-nhusb merge, and Nick
is looking into it.
