The trouble is in the latest current also.  I created new
kernel Oct 27, and got the same lock-up problem, when I
wrote data to RAID5 disk although it's full.  It's something
like this.  I received "write failed, file system is full"
message 5 times, and then received the same message once.
Kernel gone.

  Oct 28 09:25:19 sou /netbsd: uid 1000 comm perl on /mnt2: file system full
  Oct 28 09:25:20 sou last message repeated 5 times
  Oct 28 09:25:24 sou /netbsd: uid 1000 comm wget on /mnt2: file system full

I remember Oct 6 kernel or at least Sep 22 kernel wasn't
locked up in the same situation.  Now, I'm fscking file
system.  I'll try older kernels after fsck.

Ps shows different status this time.  Last time, it was
vnlock.

FYI, my /mnt2 is regular ufs without any option like softdep
on RAID5.
