I can confirm that I see the same problems in T20. The break definitely
occured somewhat between July 9 and July 15. July 9 kernel works
fine for me.

If noone replies until weekend, I'll try to find the commit which broke it.

Same with my T20. Also ACPI introduces random hangs of a working notebook
and random powerups of switched off notebook. :(
