One thing you could try next is to add a debug logging macro which prints the contents of OHCI1394_IntEventClear, OHCI1394_IntEventSet, and OHCI1394_IntMaskSet, right after ohci1394's call to hpsb_selfid_complete. (I'm merely poking in the dark here.)
I think you've got something! I managed to provoke failure from 3 of the 5 interfaces in a single burst of reset clicking! And yes, all 3 failed interfaces are on the Indigita card, and no, the Fireboard has never failed. The last thing I see from the failed interfaces is this: Nov 27 08:25:51 spanky kernel: ohci1394: fw-host3: PhyReqFilter=0000000000000000 Nov 27 08:25:51 spanky kernel: ohci1394: fw-host3: IntEventClear 00000000 IntEventSet 6ffdc33f IntMaskSet 00000000 which looks very different from the entries by the interfaces that survive (these are the lines immediately before the one above) Nov 27 08:25:51 spanky kernel: ohci1394: fw-host4: IntEventClear 00000000 IntEventSet 04508000 IntMaskSet 818300f3 Nov 27 08:25:51 spanky kernel: Nov 27 08:25:51 spanky kernel: ohci1394: fw-host2: IntEventClear 00000000 IntEventSet 04508000 IntMaskSet 818300f3 Nov 27 08:25:51 spanky kernel: I'm not sure if this says anything to you except "hey, don't use those Indigita cards". The problem is, I can't get the number of ports I need using only Fireboards (I think I need 6, and I have 5 PCI slots but need to use some of the other slots). Is there further diagnostic poking about that I can do to narrow down the problem? Is something for Indigita? The card is pretty basic: 4 of the TI TSB82AA2 (Ice Lynx) links behind a IBM/Tundra PCI-X bridge. I have an Intel quad ethernet card that uses the exact same part (well, one rev older, actually). Here's a chunk of my lspci for completeness sake: 01:04.0 PCI bridge: IBM PCI-X to PCI-X Bridge (rev 03) 01:06.0 FireWire (IEEE 1394): Texas Instruments TSB82AA2 IEEE-1394b Link Layer Controller (rev 01) 02:04.0 FireWire (IEEE 1394): Texas Instruments TSB82AA2 IEEE-1394b Link Layer Controller (rev 01) 02:05.0 FireWire (IEEE 1394): Texas Instruments TSB82AA2 IEEE-1394b Link Layer Controller (rev 01) 02:06.0 FireWire (IEEE 1394): Texas Instruments TSB82AA2 IEEE-1394b Link Layer Controller (rev 01) 02:07.0 FireWire (IEEE 1394): Texas Instruments TSB82AA2 IEEE-1394b Link Layer Controller (rev 01) I will also try cramming a machine full of Fireboards and seeing if I can't get one of them to fail. -- Robert Crocombe [EMAIL PROTECTED] - 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/
