[Bug 643714] Re: Thinkpad T410s will not suspend

[BobG]

 I am terribly sorry. I have to amend some of my earlier statements upon
further testing. There is no kernel where it works (more than once). So
it sounds like this might have more to do with the other bug.

Note that I am running Thinkpad BIOS version 1.22 and that this machine
has a touchscreen.

1. Mainline kernel test - Linux 2.6.32-02063215-generic
Suspend/resume is still broken with the mainline kernel. The symptoms changes however. With the mainline, suspend will work once. Upon resume, every thing seems fine at first but then the left mouse(trackpoint) button stops working. Trying to suspend a second time produces the same result as with the ubuntu kernel -- the screen blanks but stays on -- moving mouse brings up the login box. Mouse left click was still broken. Suspending a third time caused the machine to stop responding with a blank but powered screen -- caps lock light blinks. Also tried booting the "recovery mode" into low res graphics and behavior was similar -- one suspend/resume, second suspend worked but resume failed in the blank screen, caps lock blinking state.

2. Current upstream kernel test - Linux 2.6.36-999-generic
Every suspend attempt results in going back to the login prompt. It looks like the the machine prepares to suspend but then resumes. I tried about 5 times. The machine never became unresponsive, but it never suspended. With this kernel, when suspending it switched to a console and printed dmesg-like messages. None looked relevant to me.

3. Ubuntu kernel test - Linux 2.6.32-24 generic
Every suspend attempt results in going back to the login prompt. It looks like the the machine prepares to suspend but then resumes. I tried about 5 times. The machine never became unresponsive, but it never suspended.

4. Windows 7 test
Works every time, damn them. This seems to suggest that there is not a hardware failure on this particular machine.

5. Fresh Lucid Install test
Every suspend attempt results in going back to the login prompt. It looks like the the machine prepares to suspend but then resumes. I tried about 5 times. The machine never became unresponsive, but it never suspended. I installed from the network installer, chose "Ubuntu Desktop" and tried suspending right after it rebooted into the Ubuntu for the first time. This surprised me because I thought that suspend had worked at some point but I think now it only worked in Windows.
