It depends on it attitude at the time of crash. This may be able to be explained by Erratum #4. If the root hub were to be reset during use then there would need to be some time for the registers 34h and above to settle before re-reading them. During this time the device may be not be responsive, but I don't have the complete documentation on erratum #4. This is a verbose as it got when it crashed. Here is the error right before the IRQ was shutdown on the other computer: Apr 19 19:52:44 masigla ohci_hcd 0000:00:07.4: bogus NDP=145, rereads as NDP=4 Maybe I will put printk's in the usb_reset functions to see if it is reseting the controller, and if that is when it is crashing. Doesn't make sense why the root hub would be reset during the middle of a transfer.
