Comment 85 for bug 602049

My Ubuntu 10.10 Thinkpad X200 (2.6.35-25-generic-pae #44-Ubuntu SMP) reliably fails to suspend - it'll got through the motions, but immediately resume, leaving the laptop smoking nicely in my bag. dmesg shows:

I followed the suggestion in bug 657386 (a duplicate of this one) to successfully fix it :

ie creating '/etc/pm/config.d/unload_module' and adding SUSPEND_MODULES="tpm_tis"
