I have now found a way to reproduce the DMA problems some setups seems to be having with the SiI3112A SATA chip.
Now, if I use real SATA drives, (and I mean real SATA drives, the WD Raptor fx is not a real SATA device but just a PATA device with a build in PATA->SATA converter chip) it works just fine no matter what I try. If however I use an older PATA drive and a certain PATA->SATA "dongle" (in this case 1 out of 4 samples) I can reproduce the problem pretty easily. This suggests to me that we are looking at a timing problem of sorts the question is where. I'll work on the problem as time permits... -Søren _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
