Description Enry 2005-09-21 10:59:08 UTC

Most recent kernel where this bug did not occur: none
Distribution:Ubuntu
Hardware Environment: Acer Travelmate 427LC
Software Environment: Ubuntu Breezy
Problem Description:
Following instruction from Documentation/power/video.txt, i got sleep s3 working
with a radeon 7500 mobility.. Main issue is that usbcore module don't want to
unload, if forced i got an Ooops.. Resuming without forcing unloading i obtain
two different situation:

[with mouse plugged in]Mouse goes slow, if unplugged it will be no more
recognized from the kernel.. no other usb perpherals will be recognized..

[without mouse plugged in]It seems controller is frozen.. no dmesg entry about
any usb action un plug/unplug action...

Steps to reproduce:

I have this configuration for my 2.6.14-rc1
http://www.cs.unibo.it/~ecataldi/config-2.6.14-rc1

I use vbestate to avoid radeon problems about S3...
Go S3 through /sys/power/state
and have successfull resume but usb managing is done..

Comment 2 Enry 2005-10-15 03:20:48 UTC

I read bug #5227 and applyed patches on comments #22,#13 over 2.6.14-rc4.
The situation didn't changed..

On www.cs.unibo.it/~ecataldi/log_resume there is a dmesg log divided in 3 zones:
after resuming - after unplugging usb mouse - after plugging usb mouse.

On www.cs.unibo.it/~ecataldi/config-2.6.14-rc4-exp there is the configuration
for this attempt.

Hope this can be helpfull.
