Hi,

I am using APM at my R40 thinkpad since 2.4 kernels and it just worked.
I.e. suspend-to-ram and suspend-to-disk worked fine.

But with Kernel > 2.6.11 I get strange results. After suspending to RAM
it seems that the thinkpad sleeps for 1-2 minutes and then resumes
without user interaction automatically.

Does anyone have experienced some similiar behaviour?

I can reproduce it like that:
- press Fn+F4
- tp goes to suspend, the LED-moon gets on
- stay away from keyboard
- after max 2 Minutes tp suspends automatically

I upgraded from vanilla to vanilla kernel with make oldconfig.

I upgraded mainly because of two problems with the 2.6.11 kernel:
- after some resumes the eth0 interface blocks a few minutes. To work
  around this I have to ping some computer a few times until a
  'e100_watchdog' message appears in the kern.log
- after a random number of successful resumes I get one resume where my
  keyboard layout gets randomized. I.e. I get some 'unknown keycodes'
  messages in the kernel-logs and e.g. 'enter' is then at 'a'
