Public bug reported:
After resuming from S3 on my Turion based notebook, I have tons of the
following messages in dmesg output:
during suspend:
hub 4-0:1.0: suspend
usb usb4: suspend, may wakeup
usbdev3.1_ep81: PM: suspend 0->2, parent 3-0:1.0 already 2
hub 3-0:1.0: PM: suspend 2-->2
hub 3-0:1.0: PM: suspend 2->2, parent usb3 already 2
usbdev3.1_ep00: PM: suspend 0->2, parent usb3 already 2
usb usb3: PM: suspend 2-->2
usbdev2.1_ep81: PM: suspend 0->2, parent 2-0:1.0 already 2
etc.
and during resume:
usb 4-2: resuming
usbdev4.2_ep00: PM: resume from 0, parent 4-2 still 2
etc.
This is on a Via based chipset. This looks like a wrong sequence?
Shouldn't the children suspend before the parents? And resumed vice
versa?
