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. :( -- Totus tuus, Glebius. GLEBIUS-RIPN GLEB-RIPE
