Reboot (panic) while using 5.0.1

[Bernd Ernesti <netbsd%lists.veego.de@localhost>]

Hi,

I updated one system to 5.0.1 and got a few freezes and found this
in the dmesg log:

fatal page fault in supervisor mode
trap type 6 code 2 eip c071c67d cs 8 eflags 10246 cr2 0 ilevel 2

Has anyone an idea what that could be?

I also got a dump from savecore after I found out how to
get it:

(gdb) bt
#0  0xc0543ab2 in cpu_reboot ()
#1  0xc0488350 in panic ()
#2  0xc054679d in trap ()
#3  0xc010cb80 in calltrap ()
#4  0xc07d0d85 in memset ()

That is with the 5.0.1 i386 GENERIC kernel.

Regards,
Bernd

P.S. A memtest hasn't found any issues yet.
