i386 -current panic

[Chavdar Ivanov <ci4ic4%gmail.com@localhost>]

Hi,

Less than two days old system gives me repeatable panic - apparently
under load. I was able to take crash dump - in case anyone is
interested, http://www.spidersweb.co.uk/~ci/netbsd/ .

[loan8] /var/crash # uname -a
NetBSD loan8 5.99.43 NetBSD 5.99.43 (GENERIC) #0: Wed Jan  5 14:54:45
GMT 2011  root@uksup2:/usr/obj/usr-current/i386/sys/arch/i386/compile/GENERIC
i386

This happens running 'make test' in /usr/pkgsrc/lang/sbcl, the initial
message is as follows (manually taken):

...
uvm_fault(0xc0af500,0,1)->0xe
fatal page fault in supervisor mode
trap type 6 code 0 eip c06e3770 cs 8 eflags 10246 cr2 4 ilevel 0
kernel: supervisor trap page fault, code=0
Stopped in pid 0.48 (system) at netbsd:uvmpdpol_selectvictim+0xd0:
cmpl
$
0xc09a0ccc,0x4(%esi)

then in gdb:

(this system has been running 5.99.39 since mid-September as later
releases did panic on boot at the discovery of the system disk - sd0
on an

ahc1 at pci3 dev 9 function 0: Adaptec aic7892 Ultra160 SCSI adapter

and this was the first version I've tried for some time, which did not
do that; otherwise it has been pretty reliable, I don't think this is
hardware-related).

A second VirtualBox machine running the same release rebooted
overnight during pkg_rolling-replace; I also had one inexplicable
reset on my T61p laptop under the same version of the system, this
time amd64, but has been behaving today ( again full 'make' and 'make
test' on sbcl).

Anyone else having similar problems?
