Bug#656196: Seems fixed in 3.4

[Michael Below <below@judiz.de>]

I upgraded the kernel to 3.4 from experimental, the stall warning
doesn't appear anymore. At the same time, there are more "workaround"
messages during USB startup:

[    0.820986] ehci_hcd 0000:00:12.2: EHCI Host Controller
[    0.821020] ehci_hcd 0000:00:12.2: new USB bus registered, assigned
bus number 1

[    0.821057] ehci_hcd 0000:00:12.2: applying AMD SB600/SB700 USB
freeze workaround
[    0.821070] ehci_hcd 0000:00:12.2: debug port 1
[    0.821097] ehci_hcd 0000:00:12.2: irq 17, io mem 0xf0308400

I guess one of these helps.
Instead, I am seeing this error during shutdown:

BUG: Bad rss-counter state mm:ffff88003fbc9040 idx:1 val:-1

But that seems to be a known bug in 3.4.4, I reported it as bug #680513

Cheers
