------- Comment #58 from [EMAIL PROTECTED] 2007-12-23 16:16 ------- Created an attachment (id=14164) --> (http://bugzilla.kernel.org/attachment.cgi?id=14164&action=view) Patch to debug suspending of devices Yes, sorry for the delay. Please revert the patch from Comment #55 and apply the appended patch (please let me know in case it doesn't apply). Next, please compile the kernel with CONFIG_PM_VERBOSE set. Then, if everything goes well, there should be /sys/power/pm_drivers attribute available. There should be two numbers in it, 0 and the number of devices registered in your systems. If you echo a number (say N) between these two into /sys/power/pm_drivers, the suspend will be artificially failed after suspending N devices (ie. the suspend of device (N+1) will fail with ECANCELED). By echoing 0 to /sys/power/pm_drivers you go back to the normal behavior. Now, you can do the following: (1) suspend normally (2) after the resume, echo n/2 to /sys/power/pm_drivers, where n is the second number printed by "cat /sys/power/pm_drivers" and try to suspend (the suspend will fail) (3) see if your touchpad works (4) if it does, echo 0 to /sys/power/pm_drivers and repeat from (1), but take n/4 instead of n/2 in (2) (5) otherwise, echo 0 to /sys/power/pm_drivers and repeat from (1), but take 3n/4 instead of n/2 in (2) Repeat the procedure in the binary search fashion until you find the exact number that has to be echoed into /sys/power/pm_drivers before the second fake suspend so that the touchpad works. Next, attach the output of dmesg taken exactly at this point. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
