Last working release: 3.10

Once my PC has been hibernated and resumed, some devices plugged
in to the on-motherboard ports stop working, and don't show up in
lsusb. The pattern seems to be that ports with USB 1.1 devices
are affected, but ports with USB 2.0 devices are not.
It's an x86-amd64 desktop, with an MSI motherboard based on the
AMD 970 chipset. Ports in USB 1.1 mode use the ohci-pci driver.
I've bisected the problem to c1117afb85, included in v3.11-rc1.
c1117afb85 USB: OHCI: make ohci-pci a separate driver
If the PC is booted without a resume image, everything works.
It's running Debian unstable with a local kernel build, and to
hibernate I'm using the "pm-hibernate" script from pm-utils.
For a sanity check of my local builds, I've seen the same
behaviour in the Debian archive's build of 3.11-rc4.
Using an optical mouse as my main test device:
The mouse doesn't show up in lsusb, and the light (optical mouse)
is off. It doesn't sent any input to X11.
Plugging the mouse in to a different USB port on the motherboard
will show brief activity in usbmon, but again it doesn't work,
doesn't show in lsusb and doesn't light up.
Once the mouse has been plugged in to a USB port, no device will
be detected in that physical port again until the PC is rebooted.
Nothing will show in dmesg or usbmon when another device is
plugged or unplugged (even with CONFIG_USB_DEBUG).
USB 2.0 devices still work (but not in ports that a 1.1 device
has previously been plugged in to). An external USB 2.0 hub does
still show up after hibernation, and the same USB 1.1 mouse works
if plugged in to this hub.
Attached are logs from bd479f2933 with CONFIG_USB_DEBUG. There's
no physical movement of plugs in this log, just hibernating and
resuming with the same devices plugged in. The keyboard is PS/2,
not USB.
