You box is UP, so only i8254 is used. C3 does not affect the i8254 interrupt timer. > > So maybe this is just some sort of timing problem? > Is anyone else seeing this? I guess thinkpads are quite common here. This looks very strange, could you give me the bootverbose dmesgs: w/ ACPI, w/o usb modules w/o ACPI, w/ usb modules I think using these two combinition, your box is booting? BTW, what will happen if you load USB modules after boot? Best Regards, sephe -- Live Free or Die
