S1 and S3 on IBM Thinkpad don't work

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,

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

The dmesg, dmidecode, acpidmp, lspci and interrups files can be found at http://www.pci.uni-heidelberg.de/tc/usr/bernd/downloads/R31_acpi/

I'm having the same problem on my T41 on nearly identical hardware. I haven't had time to do any extensive testing, but even APM suspend/resume seems to be broken on 2.6.10-rc1-mm4 :(
