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.
Code changed and compiled. Unfortunately my whole machine freezes as soon as I start Jack.
*sigh*
Which hardware is connected? Did you try that with both? Did you try with anything else than jack? I'd need more information about your setup to get an idea.
