The Tyan S2466N-4M motherboards bite once again.
For various reasons I need to upgrade the software on our cluster
from Mandrake 10.1 to something a bit more modern, so I tried
Mandriva 2007. Wiped / and /boot on a test node, did
a clean install of Mandriva 2007, and pretty much
everything worked as it should. Unfortunately
this resurrected the old problem where "poweroff" leaves the machine
in a dead state: it doesn't respond to the front panel button
until the power is unplugged, 20 seconds pass, and the power is
restored. This problem was resolved the first time it showed u
Hi Dave:
We have seen this on lots of Tyan boards in general. Kind of hard to
recommend steering clear if you have a room full of them.

many years ago by upgrading to BIOS 4.06. There's no newer BIOS,
so that isn't going to fix it this time. It isn't a Mandriva 2007
problem per se because we have another machine (a very old
Athlon 850 with a Gigabyte motherboard) running that OS and it
does "poweroff" correctly. The two machines (poweroff working and
not working) have exactly the same versions of every RPM package.
LILO is pretty basic on both of them too:
image=/boot/vmlinuz
label="linux"
root=/dev/hda5
initrd=/boot/initrd.img
append="resume=/dev/hda2"
I seem to remember having to do a noacpi option to make them behave.
Something about acpi on these boards were horribly broken. FWIW we have
seen this with a few late model Opteron (Tyan) boards as well. :(
