@relik:
I have successfully worked around this problem by adding irqpoll to my kernel parameters.
1. Add "irqpoll" to the line beginning with:
# defoptions=quiet...
2. Run:
sudo update-grub
3. Reboot
Since I added irqpoll, the two USB ports on my ThinkPad X61 remain active. I've used it for days with this setting, and suspended/resumed many times. USB ports remain up.
