Interesting that acpid hosed the machine that badly. Weird!
> I want to boot with "noacpi". Where do I put that?
Edit /boot/grub/grub.conf. Find the stanza that reflects your kernel,
and edit the "kernel=" line. Put " noacpi" at the end. For example,
on my Fedora Core 4 machine:
title Fedora Core (2.6.14-1.1656_FC4)
root (hd0,0)
kernel /boot/vmlinuz-2.6.14-1.1656_FC4 ro root=LABEL=/ rhgb
quiet noacpi <<<<====NOTE!
initrd /boot/initrd-2.6.14-1.1656_FC4.img
If you just want to try it once, reboot the system. At the grub
screen scroll to the kernel you want to play with and hit "E".
Scroll down to the kernel line and hit "E" again. Go to the end of
the line and add " noacpi" to it (don't forget the leading space and
do NOT include the quote marks), then hit <ENTER> and press B. The
system will boot with noacpi THIS TIME ONLY. If you want it to be
permanent, you have to edit the grub.conf file as I mentioned above.
