Public bug reported:
Binary package hint: linux-source-2.6.20
When hibernating or suspending my laptop (ThinkPad T42, Feisty), I see
messages like this:
[ 5026.180000] usbdev4.1_ep81: PM: suspend 0->2, parent 4-0:1.0 already 2
[ 5026.180000] hub 4-0:1.0: PM: suspend 2->2, parent usb4 already 2

[ 5026.180000] usbdev1.1_ep00: PM: suspend 0->2, parent usb1 already 2
and when resuming:
[ 5031.932000] usbdev4.1_ep00: PM: resume from 0, parent usb4 still 2
[ 5031.932000] usbdev4.1_ep81: PM: resume from 0, parent 4-0:1.0 still 2
The system has no external USB devices connected at present, and I
didn't see these messages under earlier kernels. Apart from the
messages, the system seems to resume OK.
