It repeats forever (I have another 15000 lines I > didn't include). From what I can tell, the aic7xxx card is sitting in a loop waiting for its DMA of the next transaction to complete. The fxp driver seems to have similar problems with burst transfers at the same time. My guess would be that the chipset gets wedged somehow, but without chipset information from ServerWorks, this is going to be a tough nut to crack. Having a PCI bus analyzer might help as well, assuming there is a slot on either the bus fxp0 or ahc0 is sitting on. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
