I've experienced just such a hardware fault. The Infineon DSCC4 serial controller has a hardware bug in the PCI request/grant handling that can lead to the device driving the PCI bus in conflict with another device. While the results were random (as the oops in this problem seem to be), the trigger was always activating certain devices in combination. In your case, altering the timing/behavior of the serial device during open may be provoking the hardware fault. -- Paul Fulghum Microgate Systems, Ltd. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
