So, it happened again, barely a day since I applied the patch. This time I got an interesting irq kernel call trace, involving "__report_bad_irq.isra": http://dennisn.linuxd.org/guest/pubstuff/debug-usbaudio/crash7.log Not sure if it's relevant, but from the "registers" debugging file, I also noticed that this time the "fmremaining" and "FR" values were not changing over time, and the "FRT" tag is not there. Also not sure if it's relevant, but the devices are still able to get power when they're in this crashed/unresponsive state. And also, I haven't (yet) been able to reproduce this bug with a 4-port hub that I started to use. But we'll see how long that claim lasts. -- 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
