Hello!
Hi Berthold!

'shutdown -h now' doesn't work for my system (Acer Extensa 3002 WLMi)
with linux-2.6.20-rc kernels. The system reboots instead.
I've checked linux-2.6.19.1 with an almost identical .config file
(differences because of new or changed options). For pre 2.6.20 kernels
shutdown works for my computer.

Thanks for your report.

Please send:
- the .config for 2.6.20-rc2
- the output of "dmesg -s 1000000" with 2.6.20-rc2
- the output of "dmesg -s 1000000" with 2.6.19

Hello Adrian,

I've attached the informations you requested.

In additon to the poweroff problem I see a lot of messages with
linux-2.6.20-rc2 that I do not see with linux-2.6.20-rc1:

kernel: ACPI: EC: evaluating _Q80
kernel: ACPI: EC: evaluating _Q81
kernel: ACPI: EC: evaluating _Q09
kernel: ACPI: EC: evaluating _Q20

I'm running Debian testing/unstable with 'homemade' kernels. The laptop
is one of those using the Smart Battery System.


Berthold
Well, I see a lot of differences not related to ACPI...

Processor caps differ...

Yenta: Raising subordinate bus# of parent bus (#02) from #02 to #06
Berthold,
Could you please check if disabling PCMCIA changes situation?

Regards,
   Alex.




Hello Alex,

I still get the same diffs. Except the yenta part of course. And the
system is still rebooting.

Berthold
Good, yenta is cleared :) Could you replace /drivers/acpi/ec.c with the version from 2.6.19.x and try again?

Regards,
   Alex.
