Hi,

this might be a regression - have not seen this warning in 2.6.32 with identical
hardware. Btw the ageold usb-sound issue still appears present in 2.6.33.2, do not
think it is related but I mention it because it also frequently causes circular
locking warnings on my hardware.

Can you please check if this also is present in the latest 2.6.34-rc kernels
(preferably 2.6.34-rc4 when it's out)?

I can try it, or if you have a particular patch set try to apply it to 2.6.33. It is not
100% reproducible however.

Well, it's always a good idea to try the current Linus' tree.
