Which PowerEdge?  2.4.7-ac11 includes a patch to allow "SMP" reboots
reboot=bios,smp
reboot=bios

and auto-detects the need for that on the PowerEdge 300 and 1300.  SMP
reboots make sure that the reboot code runs on the bootstrap processor.
Please give this at try.

Thanks,
Matt

Compile a kernel with apm support and add the following to your
lilo.conf:

append="apm=power-off"

---------------------------------

I too am having trouble powering off and rebooting an SMP machine. It 
is a Tyan Tiger 230. I have tried to report this a few times with 
little to no response. The last kernel that worked for me in this 
respect was 2.4.6-ac2. I have tried linus' and alan's kernels both with 
no success. I have tried configuring all kernel with APM soft-power 
off, real-mode power off (I enable power-off even though the rest of APM 
is broken on SMP), ACPI (multiple setups), and nothing at all. None of 
these kernel/configuration combos allow me to shutdown or reboot my 
machine. I would like to be able to and I know the board still works 
because Windows 2000/XP (even though I hate using them) both manage to 
shutdown/reboot the machine properly. I have everything I can think of 
copiled in statically instead of as modules and also have PNPBIOS enable 
in the kernel and the BIOS. Any help would be appreciated.

The -ac kernel tree knows a lot about Dell poweredge and reboot
requirements, courtesy of the nice folks at Dell.

I'm also having problems on all my smp machines. I can't reboot reliably from a shutdown,
not even using the software watchdog daemon to help (killall -STOP watchdog), not even
from "reboot", nor from magic-sysreq (though that seems most reliable to me - maybe 80%).
I am currently using apm=power-off on 2.4.6 with about a 50% success rate overall.

When things go badly, it just sits there at the "rebooting" stage, and needs
the red button to be pressed.

The machine that most annoys me in this regard is the dell poweredge at which I am
sitting ... it's been a long time since I booted 2.2 on it, but I think things
went better.

The bios has no options vis-a-vis apm, etc.

I have been running all kernels 2.4.0 to 2.4.8. I think 2.4.8 may be a bit better,
but it needs time to get a feel for the stats.

Re: Shutdown and power off on a multi-processor machine

[Pozsar Balazs]

I had the same problems, and the only way i could have a poweroff at
shutdown was to pass the apm=power-off option to the kernel at boot time.
(e.g. in lilo.conf, have a append="apm=power-off" line.)

Hope that helps,
Balazs Pozsar.

Shutdown and power off on a multi-processor machine

[Shawn McGovern]

I have a need for a headless machine to power off at the end of shutdown,
but cannot get it to work for smp kernels. I tried 2.2.14, and 2.4.9,
built with smp and apm. If there is a way to make this work, I would
really appreciate any advice. If it cannot be done I would sure like to
know that too, so I can stop banging my head on this particular wall.
Please send responses to me directly as I am not on this list. TIA.

Cheers,
Shawn
