Kernel panic on amd64/current

   I've tried sending this before, but it looks like it
never went
out. This time I'm including links instead of the whole
text. Sorry
for any dups...

   With current kernel, amd64 platform, moderate activity, I
get:

============================================================
===============
kernel: privileged instruction fault trap, code=0

Stopped in pid 4.22.1 (cvs) at  netbsd:uiomove+0xd3: testb 
%cl, 0xffffffff8514247c(%rbx)
============================================================
===============

   This was doing a CVS update of pkgsrc, but I also see
hangs when
working in X. (I don't have a serial console, so I can't see
the
message in that case.) A kernel from a few weeks ago (same
config)
works fine on the same hardware:

NetBSD capo 4.99.13 NetBSD 4.99.13 (CAPO64) #3: Tue Mar  6
08:43:08 EST 2007  garycapo:/usr/obj/sys/arch/amd64/compile.amd64/CAPO64
amd64

   dmesg output and kernel config available here:
