I suspected it as well, though the panic also happens when accessing the
MFS filesystem after booting from floppy.  With or without the twe card
in the system.  I thought that was convincing.  :-)

No, but I did try fiddling with memory sticks again.  One of them is
clearly bad -- with just it, the system won't even get through the BIOS,
and with the other one I've gotten all the way to a running system.

However, it's not out of the woods yet as I've seen several panics
during shutdown.  Here's one that I caught on paper:

   syncing disks... 1
   done
   vm_page_free: pindex(57), busy(0), PG_BUSY(1), hold(0)
   panic: vm_page_free: freeing free page
   Uptime: 3m3s
   twe0: Cannot delete unit. error = 16

I'm going to run Memtest86 on the box overnight, and also try 5.3-BETA
for which I ran out of time last evening.

I'll give it a whirl.  However, this machine is destined to be my main
web and mail server so I want something very stable.  That's why I have
been planning to use 4.10 rather than 5.x, which in turn forces i386.
I mainly bought the K8V for lots of ECC memory, not because I need the
horsepower, though if 5.3(-BETA) is stable and the amd64 buys enough
performance it could be interesting for web site upgrades.  One of mine
(gc.kls2.com) is quite busy and enough CPU could enable some interesting
enhancements.

More tonight.
