Description of problem:
If I disconnect a usb device (like a bluetooth dongle) while the
laptop is in standby, resume will not complete: the last message
visible on the console is:
"usb 1-1: control timeout on ep0in"
If I then plug the bluetooth dongle back in, the resume process
recovers and everything behaves normal.
I never had this problem on kernels <= 2.6.8 or 2.4 kernels.
Version-Release number of selected component (if applicable):
all 2.6.9 versions of fc3test kernels
Steps to Reproduce:
1. suspend the laptop with a usb device connected (echo -n "mem" >
2. disconnect the device while the laptop is in standby
3. bring the laptop out of standby
This bug appears fixed in 2.6.10 and later kernels
