Hello Daniel,
I'm now running this new patch with the kernel git 3.2 rc6.
I do get sound through Alsa and Pulse Audio, but Jackd2 crashes at start. The same version of jack works on 3.2 rc4 with your previous version of the patch.
Let me know if there is any other info that I should provide you outside the dmesg trace below.
In dmesg, I get the following: [ 92.185624] BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 [ 92.185637] IP: [<ffffffffa05c9768>] snd_usb_endpoint_activate+0x18/0x90 [snd_usb_audio]
Can you do a quick fix and add the following two lines right at the beginning of snd_usb_endpoint_activate() in sound/usb/endpoint.c:
if (!ep) return 0;
? I'll fix this in a nicer way, but that should work.
Thanks, Daniel
