Severity: serious
Hi,
I've experienced this regression from squeeze, so I'm noting it before
I forget and wheezy's released...
I have a desktop machine with a motherboard that has an AMD SB 750
south bridge with an integrated USB controller.
With Linux 2.6.38, custom built, and pretty much all earlier versions,
the Logitech K350 keyboard, plugged in through that little unifying receiver,
works fine, as does the Logitech LX8 mouse, plugged in through its own,
slightly larger receiver.
When I boot the Debian kernel 3.2.x with an initrd, the machine freezes on
boot before the initrd processing starts, strangely enough.
I built my own copy of 3.2.27 with .config from 2.6.38 + make oldconfig,
and it booted, but the keyboard simply didn't work.
Googling brought up some similar problems, but nothing seems to be exactly
the same:

This half-hour investigation was all the time I had for this this weekend.
I'll try to do more and attach more information here as soon as I get a
chance. A git bisect would probably be quick enough, but I didn't have a
checkout handy at the time.
