Description Neil Sherman 2005-09-05 17:12:58 UTC

I am using an HP Special Edition L2000.
When I choose to turn off the system, Linux appears to shutdown properly.  As I
watch the messages scroll down the screen I see the message:
"The system will be halted immediately."  as I would expect; however, the
computer does not power off, it reboots instead.  If I let the computer reboot
and then select to turn it off again, it will shutdown and power off as it
should.  However, when I power it on again, it will again reboot on the first
turn off request but will turn off when I choose turn off the second time.  This
bug may be related to #115018 which my computer was suffering from prior to Beta 4.

Comment 4 Neil Sherman 2005-09-05 17:20:59 UTC

Although the machine is currently being run standalone (not connected to a
network), it is being started at runlevel=5 which is the normal runlevel I would
be using it in.  Not sure if that bit of info will help.  I've not tried
shutting down from other runlevels.

Comment 5 Neil Sherman 2005-09-06 03:13:45 UTC

The behavior I noticed this morning is no longer consistent.  Now my machine
always reboots rather than turning off on the 2nd request for it to turn off. 
The one difference I can think of is that I left the machine on at the login
prompt for quite awhile (the screen had gone blank) this evening.  I can't
imagine how that could affect anything.

Comment 6 Neil Sherman 2005-09-19 23:55:38 UTC

This problem was originally detected in Beta 4 and still exists in RC1.  I have
found for no logical reason that the computer will occasionally shutdown as it
should; however, more often than not, it simply reboots.

Comment 7 Andreas Kleen 2005-09-28 15:25:30 UTC

Sounds like a BIOS problem, unlikely we can do much.

Can you connect a serial console and boot with console=ttyS0,baudrate
and attach the log of the failed reboot? Test the serial cable on the 
running system first.

Comment 8 Neil Sherman 2005-10-01 19:54:40 UTC

There is no serial port and I have no console.  However, I went to the HP
website and downloaded an updated BIOS image.  I flashed the BIOS and verified
on boot up that the BIOS version number had changed.  I reloaded 10 RC1 from
scratch and it still failed to shutdown the notebook.  If I reload the Windows
XP Home SP2 CD that came with the laptop, I can restart or shutdown the notebook
normally.  If there is a BIOS problem, the Windows CD supplied by HP with the
notebook must have been modified to deal with the problem.

Comment 9 Neil Sherman 2005-10-04 01:50:07 UTC

My comment #8 doesn't help much because I cannot provide any log entries.  Is
there another way to get the information you need without using the serial port?
 As Novell, have you any way to contact HP to determine if there is some
difference in their notebook BIOS or motherboards that is new and unknown to Linux?

Comment 10 Neil Sherman 2005-10-20 23:36:30 UTC

Tests with DSLinux, PuppyLinux, Kanotix, and SUSE Linux 9.3 Live showed that the notebook could be restarted or shutdown properly.  Apparently there is something in commercial SUSE 9.3 and OpenSUSE 10.0 RC1 that conflicts with shutting down the computer.  I'll have to keep at this until I can determine the cause.

Comment 11 Alexander Osthof 2006-07-10 14:21:22 UTC

Have you already tried SUSE 10.1 and if you did, does the problem still exist?

Comment 12 Neil Sherman 2006-07-11 04:02:03 UTC

SuSE 10.1 seems to be working fine for me with regard to shutdowns.
