Now I'm not sure if it's a regression, because it happens not every boot. Maybe I just noticed it after 2.6.30 jiri, I found the place via extra printk messages added to the i8042.c in function i8042_check_aux(), when touchpad detecting fail, it fall into following error path: if (wait_for_completion_timeout(&i8042_aux_irq_delivered, msecs_to_jiffies(250)) == 0) { [snip] } so maybe the timeout value need to be increased? I try redo the i8042_setup_aux after it fails, it fixes the problem indeed, which one is the proper fix do you think? If it's the right fix I can post the patch. > > > Bug-Entry       : http://bugzilla.kernel.org/show_bug.cgi?id=13837 > Subject         : Input : regression - touchpad not detected > Submitter       : Dave Young > Date            : 2009-07-17 07:13 (10 days old) > References      : http://marc.info/?l=linux-kernel&m=124780763701571&w=4 > > > -- Regards dave -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
