I mean the usb I would think it is too early to conclude without debug. If you suspect that, is it possible to get a different platform to test, for example BeagleBone? > works fine with networking, mass media etc..And the lockup is a total Audio uses ISO transfers, network or MSC mainly uses BULK transfers. One use case works does not mean all usb use cases will work. > freeze, I can think of interrupts left disabled by software could cause total freezing does not rule out MUSB driver, I had a case (about a year ago) with g_ether which causes CPPI driver waiting for an event which never happened, so the system was completely locked up. all I meant is that it is hard to conclude without investigation. -Bin. > something like that but wouldn't it be probable that such kernel bug > would we triggered by other usb usage as well (and get noticed by lots > of people) ? > > Thanks, > Mika > -- 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
