Though we've been carrying it in our Chrome OS tree and it's been helping, in my reboot tests I did just find a crash right in the code that this patch is adding. Apparently "qh->channel" is NULL in at least some case in the loop. This seems like something that could have happened if dwc2_deactivate_qh() was called and then we got an interrupt after. I also realized that it's probably important to get order right even for non-periodic splits. lyz's patch only handled periodic splits... -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
