  I tried the diffs and had a system lockup.  The following 2 messages
were on the console:

ahc0: WARNING no command for scb2 (cmdcmplt)
QOUTCNT == 0
ahc0: WARNING no command for scb19 (cmdcmplt)
QOUTCNT == 0

  The KB LEDs worked, external pings worked and I could switch virtual
consoles.  KB chars were echoed but no further action.

  The system is a 128MB Pentium 133, DTK motherboard, Adaptec 2940UW,
3 Micropolis 2GB 4221 drives, 1 16GB Mylex RAID (external wide), and 2
ethernet adapters.  It will hopefully become an additional news server
to supplement my other bsdi servers.  The above crashes occurred while
receiving a news feed.  (I did add a quirk to the kernel so that
multiple luns would be recognized on the Mylex array although I'm not
using multiple luns at the moment.)

  The system ran for probably half an hour with the diffs before
turning on the news spigot.  After several minutes of feeding, the
crash occurred.  Since it takes a considerable amount of time to fsck
the large news spool, I reverted to the previous kernel.

  Let me know if I can provide further info or other assistance.

  Here's the kernel config and dmesg (a verbose dmesg always has the
front end truncated):
