Description of problem: When doing a "poweroff", the system doesn't physically power off. After the power down message, nothing happens. But: when I *then* do CTRL-ALT-DEL, I get the "md" message for the 2nd time, then the really powers down (fans are stopping) and after that it immediately starts again! Version-Release number of selected component (if applicable): kernel 2.4.20-2.2 Configuration: Supermicro P45BE mainboard, Intel 845 chipset. This is a new system, so it might be due to some BIOS option, but I installed systems of the same type many times with RH 7.3 and RH 8.0 and never saw this behaviour.
does it help if you add "acpi=off" to the kernel commandline ("a" key in grub, or the vmlinuz line in /boot/grub/grub.conf) ?
Yep, with acpi=off it properly powers off...
Same thing here. PC will not power off. acpi=off does not work for me however. APM has never shut this board down in the past though. SOYO Dragon mobo
Similar problem here on a sony vaio. When I type "poweroff" I'll get a kernel panic at the end and the oops messges will scroll by in an infinite loop. Turning of acpi this does not happen. Morover, this also does not happen with a stock 2.4.20 kernel + latest acpi patch.
Is this a duplicate of bug 80360?
Seems to be a duplicate of 80360, yes.
