Details

After upgrading to kernel 3.2, my system had got to freeze when trying to pm-suspend.
There was no useful messages in the logs.
After experimenting some methods described in http://www.mjmwired.net/kernel/Documentation/power/basic-pm-debugging.txt, I found this problem was caused by a module 'tpm_infineon'.
"modprobe -r tpm_infineon" or SUSPEND_MODULES="tpm_infineon" in /etc/pm/config.d have fixed this problem and pm-suspend has come to work again.
This is only a workaround, so I report this issue as a bug.

I attach some information when this problem had occured.
   dmesg.txt (60.4 KiB)
   pm-suspend.log (4.9 KiB)
   mysystem_spec.txt (25.8 KiB)
This task depends upon

Still an issue with 3.3 series?

Yes, this issue still exists on kernel 3.3.5
But the workaround above works fine, so I don't care when this problem will be fixed...
