Description Martin Mokrejs 2005-08-04 22:00:32 UTC 
Most recent kernel where this bug did not occur: 2.6.12
Distribution: Gentoo
Hardware Environment: ASUS P4C800E-Deluxe, BIOS 1.19
Software Environment:

Still broken in 2.6.13-rc5-git2.

Problem Description:

Doing "init 0" turns the power off but the power comes up immediately again.
Is not fixed by turning wither on or off kexec, nor hangcheck timer.
It was reported on lkml under thread "init 0 stopped working" and confirmed on
ASUS P4P800, BIOS 1.19 whereas 2.6.12.1 works good.

Maybe it is related to this (or same):

So it seems there are more boxes out there suffering from the same 
problem I reported some days ago

michal.k.k.piotrowski@gmail.com reported that on the P4P800 machine on lkml, but
is not registered in bugzilla so cannot be Cc:ed. :(
Comment 2 Martin Mokrejs 2005-08-06 14:23:41 UTC 
Fixed in 2.6.13.rc5-git4 or at least two attempts worked so far.
