PS, this is the state of the card just now after this failure: 10:00.0 FireWire (IEEE 1394): VIA Technologies, Inc. VT6315 Series Firewire Controller (rev 01) (prog-if 10 [OHCI]) Subsystem: VIA Technologies, Inc. VT6315 Series Firewire Controller Flags: bus master, fast devsel, latency 0, IRQ 74 $ grep "74:" /proc/interrupts 74: 132906417 17969317 15309448 18166551 42716375 33292391 30609551 28301206 PCI-MSI-edge firewire_ohci I am used to defective MSI support manifesting itself right after driver initialization, not after long periods of use with, say, 319271256 proper interrupts before it goes belly-up. And indeed, the issue with VT6315 rev 0 was an instantaneous malfunction, not a rare and random one (http://linux.derkeiler.com/Mailing-Lists/Kernel/2010-12/msg02301.html). I wonder what's up with my VT6315 rev 1. -- Stefan Richter -=====-====- -==- -=-== http://arcgraph.de/sr/ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
