After applying this, I can start jackd, record a couple of minutes worth
of eight tracks in ardour, and stop jackd again with no problems.
For the record, without the patch, as soon as I start jackd I get:
ehci_hcd 0000:00:03.3: fatal command 010010 (park)=0 ithresh=1 Periodic
period=1024 HALT
ehci_hcd 0000:00:03.3: fatal status 4008 Periodic FLR
and my computer freezes, so that's definite progress. Thank you!
There seems to be another bug in either the EHCI or the snd-usb-audio
driver; I'm still getting problems with high speed iso transfers.
I'm investigating this.
Do let me know if there's anything else you'd like me to test.
