Can you revert commit e9ba389c5 ("ALSA: usb-audio: Fix scheduling-while-atomic bug in PCM capture stream") and see if that

I can try that, but it takes a long time to build a new kernel on my old hardware.

helps? If not, can you summarize again which kernels still work for you and which don't?

The latest kernel that works is 3.6.0-0.rc2.git1.2.fc18. The earliest that doesn't work is 3.6.0-0.rc2.git2.1.fc18.

The report you sent doesn't look like it could be caused by e9ba389c5. It fixes a kernel Ooops. But as it is the only relevant patch in that area, it would be interesting if reverting it fixes anything.

Yep, agreed. If this revert kernel doesn't work, we're likely down to a git bisect, Bruno.

Yes, please. I'm currently traveling for KS and Plumbers, so I cannot debug it deeply, unfortunately.

If the culprit were really my patch, I still don't figure out why it breaks. In that case, it must be really a subtle timing issue...

thanks,
