I wouldn't expect the patch to the USB EHCI driver to have any effect on SD card speed. The big write performance hits are worrisome, though. I'd be good to test on one kernel version with and without the patch just to make sure. Also comparing SD performance with and without nosmp passed on cmdline would be interesting. --Mark _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
