Hi All,
A bug reporter noted their Dell OptiPlex 760 hangs on reboot unless
reboot=bios is specified. They have confirmed the following reboot
quirk resolves the issue. Please consider applying for 2.6.33.
Thanks,
Leann

Could we find out if reboot=acpi works on this machine?

Sure, I'll ask the reporter to confirm.

>From the bug reporter:
"It seems that reboot=acpi does not work.
I installed 2.6.33-rc6 (from today) and rebooted successfully 4 times
after booting with reboot=bios, like before. I then changed the boot
parameter to reboot=acpi. After booting with this the first time, the
computer came back up successfully after a reboot. The next time,
however, the computer didn't come back up.
Since I have moved to Norway and the two affected computers are located
in Canada I had to do this via ssh and playing with /etc/default/grub
and update-grub. I can't hit the power button or verify that it wasn't
something else that went wrong. I hope this testing is sufficient. If
necessary, I can try without any reboot option with 2.6.33-rc6 once
someone comes to work after the weekend and gives it a power cycle."
