This much reminds me this bug report: http://bugzilla.kernel.org/show_bug.cgi?id=2899 Please read the whole thread and confirm, or detail why your case is different. Next step would be to apply the proposed patch and recompile your kernel, including "I2C chip debugging messages", then compare a working case with a failing one, and report. I suspect that reads are sometimes wrong with no error reported, due to the BIOS messing up with the SMBus. If that's the case there's (unfortunately) not much we can do... > BTW: I had to change pwmconfig a bit for it to detect the fanX_pwm > lines of the asb100. In it s current state it only finds pwmX .
