Description Russell Steffen 2001-04-19 00:52:21 UTC
Hardware: Dell Poweredge 1300, 256MB, Dual PIII-500, PERC-2SC RAID 
controller

Rebooting the machine (either with "shutdown -r" or "reboot" or with 
ctrl-alt-del) causes the machine to hang instead of resetting. The last 
messages printed are:

Please stand by while rebooting the system.
stopping all md devices
Restarting system.

At this point the machine hangs, (ctrl-alt-del has no effect) and can 
only be restarted with manual intervention.

This only happens with the -smp and -enterprise kernels. The 
uni-processor-only kernel functions as expected.

Comment 1 Arjan van de Ven 2001-04-19 08:34:35 UTC
Can you try to use the following options as commandline options on the
 lilo-prompt? 
 reboot=c
 reboot=h
 reboot=b
 reboot=w
They change the algorithm with which the kernel tries to reboot.

Comment 2 Russell Steffen 2001-04-19 16:28:55 UTC
Using "reboot=b" works. All of the other reboot settings fail as desacribed 
on this machine.

I'm adding "reboot=b" to lilo.conf to make it permanent.



Comment 3 Arjan van de Ven 2001-04-19 16:39:25 UTC
Could you please run the attached program on your machine and attach the output
to this bug? (or mail me in private)
It will give us information (eg vendor and version) about the bios you have and
allows us to make "=b" the default for that specific bios in future kernels.
