Subject: reboot problem with VIA EPIA-MS motherboard
Date: Mon, 28 Mar 2005 13:08:05 +0200 [thread overview]
Message-ID: <84fecab05032803082415448f@mail.gmail.com> (raw)
Hi all,
please Cc to me your clues on the following problem:
Symptom:
"reboot" or "shutdown -r now" on VIA EPIA-MS motherboard finishes all
processes, then comes message "Restarting system.", keyboard LEDs
flash and nothing happens anymore -- one has to finalize reboot manually.
Comments:
1. Motherboard is really able to reboot: e.g. when after POST comes grub, one
could enter grub's console and issue "reboot" -- it works fine.
2. different kernel boot options were tried without success, like
"reboot=b|w|h|c", "acpi=on|off|force", "apm=on|off" -- not in
all combinations though ;)
3. Linux distro used -- Gentoo. (synced)
4. different 2.6.x kernel were tried: 2.6.9-2.6.12, not only vanilla kernels,
but Gentoo kernels too. (Now I am stuck to 2.6.12-rc1 as it is exposed via
Gentoo portage system)
5. different kernel boot options lead to different reboot implementations.
One of tracked by me implementations ends up in
mach-default/mach_reboot.h, inlined function "mach_reboot".
The second udelay(50) in the loop is the last call,
after which nothing happens anymore.
6. Any other details/logs might be posted -- just tell me
which are of interest.
TIA,
Valery.
P.S. perhaps, I do not violate any rules posting my problem and comments
to this malinglist.
