Description Chris Adams 2001-01-17 05:33:27 UTC

When I run "poweroff" (as root), it does a normal shutdown and then reboots
instead of powering off.  It works in 7.0 (and 6.2).

Comment 1 Bill Nottingham 2001-01-17 17:51:27 UTC

SysVinit didn't change how it called poweroff/reboot/etc. Sounds like it's a
kernel problem in the APM support.

Comment 2 Glen Foster 2001-01-17 18:22:04 UTC

This defect is considered MUST-FIX for Florence Gold release

Comment 3 Chris Adams 2001-01-17 19:25:16 UTC

Hmm...  My main install on this computer is 7.0 (actually
6.9.8, RC2 - I haven't had a chance to upgrade yet).  I do test
installs to a different hard drive.  I've upgraded the 6.9.8
install to kernel 2.4.0-prerelease (again, haven't had a chance
to upgrade to -release), and it powers off on shutdown just
fine.

I'll try to dig some more and see if I can figure out what is
happening.

Comment 4 Michael K. Johnson 2001-01-19 19:24:35 UTC

Since we're now based on 2.4.0-ac9, I'll assume that the fix
has been included.  Re-open this bug report if 2.4.0-0.99.5
or later still has this bug.  Thanks!

Comment 5 Chris Adams 2001-01-21 22:29:56 UTC

The newer kernel didn't help.

After some recompiles and testing, it appears that the problem is with
the CONFIG_APM_REAL_MODE_POWER_OFF option.  If I recompile the kernel
with the i586 non-SMP config except for turning this option off, I can
power off on "poweroff" just fine.

This is an EpOX EP-MVP3G2 motherboard with the VIA MVP3 chipset and an
AMD K6-III CPU.  I've got the latest BIOS on it from 12/21/2000.

Comment 6 Arjan van de Ven 2001-01-23 10:03:57 UTC

CONFIG_APM_REAL_MODE_POWER_OFF works fro about half the machines I've seen,
and doesn't for the others. Unfortionatly, disabling it is no option as there
have been reports of broken bioses doing very evil things in that case.

Comment 7 Stephen Rasku 2001-01-31 08:54:09 UTC

I am also seeing this on a Asus K7M motherboard.  7.0 works fine.

Comment 8 Stephen Rasku 2001-02-08 09:05:49 UTC

Still happening on beta3.

Comment 9 Arjan van de Ven 2001-02-14 10:08:31 UTC

This will be fixed by disabling READ_MODE_POWEROFF in the next
Rawhide kernel we build (version 2.4.1-0.1.6 or later).
If these kernels does not fix the problem for you, please reopen this
bug.
