OK, so I tried, and what can I deduce from this: I configured fwe0 on both and pinged from A to B, no response was received: B crashed (ok, so I assume this means it doesn't work). Interestingly, this one has a Ricoh R5C552 chipset which should be supported. But, it could be a conflict on the PCI-Cardbus bridge with the same IRQ? On A, this output appeared in dmesg: fwohci0: BUS reset fwohci0: node_id=0xc000ffc1, gen=3, CYCLEMASTER mode firewire0: 2 nodes, maxhop <= 1, cable IRM = 1 (me) firewire0: bus manager 1 (me) fwohci0: BUS reset fwohci0: node_id=0x8000ffc0, gen=4, non CYCLEMASTER mode firewire0: 2 nodes, maxhop <= 1, cable IRM = 1 firewire0: bus manager 1 firewire0: New S400 device ID:00e0180003094339 fwohci0: BUS reset fwohci0: node_id=0xc000ffc0, gen=5, CYCLEMASTER mode firewire0: 1 nodes, maxhop <= 0, cable IRM = 0 (me) firewire0: bus manager 0 (me) Does this mean it works? (the last 4 lines appeared after the other machine crashed). The interesting thing is that this one has a Texas Instruments PCI7x20 1394a-2000 OHCI Two-Port PHY/Link-Layer Controller, attached to a Texas Instruments PCI7420 FireWire + CardBuss bridge. None are on the hardware list (R6.1). The bridge also have a Texas Instruments "PCI7420/PCI7620 Dual Socket CardBus and Smart Card Cont. w/ 1394a-2000 OHCI Two-Port PHY/Link-Layer Cont. and SD/MS-Pro Sockets" attached which doesn't work. I'd be happy if things work on A, as this is my new machine :) Thanks, Erik -- Ph: +34.666334818 web: http://www.locolomo.org X.509 Certificate: http://www.locolomo.org/crt/8D03551FFCE04F0C.crt Key ID: 69:79:B8:2C:E3:8F:E7:BE:5D:C3:C3:B1:74:62:B8:3F:9F:1F:69:B9
