T61 suspend to ram immediately resumes

Bug Description

Suspend to RAM worked correctly on this laptop with Ubuntu 7.10, but running Hardy, it is very unreliable. It occasionally works, but most of the time, it immediately wakes up again. I haven't established any pattern to when it does or doesn't work.

A log showing a complete suspend/resume cycle is attached.

Here's the cleaned up kern.log. Doesn't show much other than a huge spew of ACPI errors.

Matt, is there any BIOS update for your system? Can you attach a full `dmesg` output of a suspend resume cycle please?

I've tried a few times today, and have been unable to reproduce this with
current Hardy. It seems this may only happen under certain circumstances,
but when it has happened, it has been persistent.

Are the ACPI errors meaningful to you?

I reviewed the BIOS updates at
http://www-307.ibm.com/pc/support/site.wss/MIGR-68451.html and didn't see
anything notable relating to suspend/resume, but I've downloaded it and will
install it as a matter of good practice.

I'm attaching a full kern.log from a (normally functioning) suspend/resume cycle.

I have the same problem on my R61. Appears to be the same bug as <a href="https://bugs.launchpad.net/ubuntu/+bug/191613">191613</A>

This is still happening with a fully up-to-date Hardy system.

Ben, any progress?

I've upgraded my BIOS to version 7LETB0WW (2.10-1.08). This seemed to get my other two USB ports working, which was another mystery with this laptop.

The first suspend/resume cycle since the reboot succeeded, but since this was not consistent, I'll have to wait and see whether this makes any difference.

I had this problem on my R61 w/NVIDIA drivers. I enabled the Bluetooth radio. Suspend stays suspended and resumes just fine now.

Try enabling your Bluetooth radio:

# echo enable > /proc/acpi/ibm/bluetooth

As of today this is working for me on an R61 with intel 965 graphics. my bluetooth is not enabled. I tried it 5 times and rebooted once and it still worked twice.

Weird.

My bluetooth radio is already enabled (and suspend to RAM is also working at
the moment). I tried disabling it (both via /proc and with the RF kill
switch), and it didn't change anything here.

That is what worked for me last night, but now things seem to be working when the radio is on and off. That was the only change I made and it started working. Maybe a different update came in yesterday that fixed the problem.

I'm unable to reproduce a problem after having upgraded my BIOS, so I'm closing this bug.

If others are still having problems after the upgrade, they should file separate bugs.
