I've observed the same behavior on a Compaq Professional Workstation SP700

You can change the reboot method but really its up to the BIOS to restart
correctly from a hard
reset as Linux does.

There are several options for rebooting a PC. Linux defaults to a cold reboot
via reset

w - warm reboot
c - cold reboot (default)

and the methods

b - bios reboot
h - hard reboot (default)

You can set these on the boot comand line by eg

Lilo: linux reboot=b,c     (for a cold bios reboot)

If that works then you can use append= in lilo.conf to set it by default

Fundamentally though I dont think its a Linux problem, let me know if the b,c
cures it on these
compaqs though.

I have the same problem on an AP400, and
no combination of warm/cold, biod/hard fixes it.

None of the previous comments seem to mention that in
6.2 (for example), there is no problem with rebooting.
Does rh7.0 do something different from rh6.2?

I'm experiencing the same sort of problem with a Compaq Deskpro 4000
P5 233, 128MB memory, standard RH 7.0.
On a warm reboot, booting gets stuck on lilo's `L', same with reboot=b,c
in lilo.conf
Hard reboots work fine.

There's no diagnostics partition anymore on this machine, and Linux boots of
a SCSI disk attached to an Adaptec PCI SCSI card.

alan,

i have the same problen on my presario 4508 duel boot with nt, i have a 12 meg
fat, then installed nt, by default the nt loader and noot.ini will be installed
on the fat partition, i then upgraded from 6.1 to 7.0 and the system will not
reboot, i have to shutdown then turn off/on the system to boot, yes lilo is
installed in the mbr, forgive me if i seam to be a novice but what must the boot
line look like in lilo.conf to add the b,c parameter, i assume after i edit
lilo.cong i can just run /sbin/lilo to update lilo.cong, here is my current
lilo.conf.

boot = /dev/hda
timeout = 50
compact
linear
prompt
   message = /boot/message
   default = linux
   vga = normal
   read-only
map=/boot/map
install=/boot/boot.b
image = /boot/vmlinuz-2.2.16-22
   label = linux
   root = /dev/hda7
other = /dev/hda1
   label = dos

thanx
kjt

The problem is still in RH7.1

Hello there!

I had a similar problem on a Clevo 2700S laptop. I simply solved it
putting the option:
reboot=bios
among the arguments of the kernel line in grub.conf.

Many thanks to everybody.
