S1 and S3 on IBM Thinkpad don't work

[Bernd Schubert <bernd-schubert-S0/GAf8tV78@public.gmane.org>]

Hello, 

I just submitted a bugzilla bugreport 
(http://bugme.osdl.org/show_bug.cgi?id=3723) since the S1 mode doesn't work 
*anymore*, see below for more details. Unfortunately S3 is also not working, 
when it wakes up, it spins up the drive, neither the display nor the network 
come up. Any help getting one of the modes working is highly appreciated. I'm 
willing to add any wakeup, sounds, reading documentation, etc. from next 
Monday on (not earlier as I'm on a conference from Thursday to Sunday).

Thanks a lot in advance,
 Bernd




Details about the S1 mode problem reported in Bugzilla:


Distribution: Debian
Hardware Environment: IBM Thinkpad R31
Software Environment: 
Problem Description:

Before and with 2.6.2-rc2 S1 was (almost) working fine, only the display 
didn't switch off. The next kernel I used was 2.6.5 and since this or a 
version between 2.6.2-rc2 and 2.6.5 waking up from the S1 sleeping mode just 
doesn't work anymore. 
Sending it to sleep mode with "echo 1 >/proc/acpi/sleep" works as usual 
(the display doesn't switch off as usual), but when it wakes up, the last line 
it prints is:

PCI: Setting latency timer of device 0000:00:1f.5 to 64

Afterwards no further keyboard input is possible and only a hard reset by 
pressing the power button for 5 seconds works. 
Possibly the other wakeup messages are also important, so I uploaded a digicam 
screenshot

It might be also interesting that this doens't happen, if I enable full 
debugging via /proc/acpi/debug_level. Well, my whole screen is then 
overwritten with lots of debugging messages, but after S1 sleeping, it wakes 
up fine.


Steps to reproduce:
echo 1 >/proc/acpi/sleep
