Subject: regression in 2.6.23-rc8 - power off failed on old laptop

Hi,

the latest kernel does not power off my old laptop.

2.6.22 succeeded
2.6.23-rc8 failed

$ git bisect good
Bisecting: 0 revisions left to test after this
[626073132b381684c4983e0d911e9aceb32e2cbc] Assembly header and main routine for new x86 setup code

Which more info is needed?

Wolfgang

A description of the system, your .config file, kernel messages (old and
new).

Also see http://marc.info/[email protected] for a highly
useful debugging step, especially if you can dump both before & after.

Okay, I just went back and looked at it... this particular checkin had
*zero* code impact (code not yet turned on), as did any of the checkins
immediately surrounding it.

Since your other email points to
f216cc3748a3a22c2b99390fddcdafa0583791a2, which is a *much* later
checkin, and which seems to actually have something to do with power
states, that the above is a red herring?

Laptop (about 10 years old, runs perfectly with 2.6.22) from
Siemens Nixdorf, Mobile 710, Pentium MMX 166
$ lspci
00:00.0 Host bridge: Intel Corporation 430TX - 82439TX MTXC (rev 01)

00:01.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01)

00:14.1 CardBus bridge: Cirrus Logic PD 6832 PCMCIA/CardBus Ctrlr (rev c1)

The last kernel messages written from the screen:

----- good case -----
Deactivating swap...done.
Will now halt.
Shutdown: hda
Power down.
(power off)
I'm not absolutely shure about the messages because it runs very fast.

----- bad case -----
Deactivating swap...done.
Will now halt.
Shutdown: hda
System halted.
_ (blinking cursor)

.config is attached.

Thankyou,
Wolfgang
