usb broken after S3 resume
Last modified: 2006-07-10 13:30:12 UTC
Most recent kernel where this bug did not occur: none
Hardware Environment: Acer Travelmate 427LC
Software Environment: Ubuntu Breezy
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
I use vbestate to avoid radeon problems about S3...
Go S3 through /sys/power/state
and have successfull resume but usb managing is done..
see also bug #5227
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.
What is the status of this issue in kernel 126.96.36.199?
Please reopen this bug if it's still present in kernel 2.6.17.
