Re: spurious reboot

I saw spurious reboots as well, but I thought it was fixed. I can't
remember when it was fixed (earlier this year?) but you should be able
to find it in the archives.

I have a two new machines that exhibit spurious reboots without panics.
The problem arise on both, hence I suspected memory to fit badly with
the chipset. But memtest ran 16 passes without finding anything wrong.

Moreover, I have been able to acheive stability by using an amd64 kernel
or a -current i386 kernel, which suggests a kernel bug, or a hardware
problem worked around by a kernel fix.

The machine has 2 DIMMs of 4 GB of RAM. NetBSD-6.0/i386 GENERIC only
sees 2 GB. Using PAE or amd64, all memory is seen.

Here are my findings so far:
NetBSD-6.0/i386 GENERIC         spurious reboots, sees only 2 GB
NetBSD-6.0/i386 GENERIC+PAE     spurious reboots, sees all memory
latest netbsd-6/i386 GENERIC+PAE spurious reboots, sees all memory
NetBSD-6.0/amd64 GENERIC        stable, works fine
latest netbsd-current/i386 GENERIC+PAE stable, works fine.

Does that rings a bell to someone? Is there some fixes in -current i386
that could be puled upto netbsd-6 ?
