> > Random failure could happen because of missing calls to DMA syncs in the driver. we have tested several drivers and cards, these show the same behavior -a- Highpoint RocketRAID 1640 HTP374 (PCI) -b- HighPoint RocketRAID 2224Marvell MV88SX6081 (PCI-X) -c- SYBA-SY-PCX40009Silicon Image Sil3124 (PCI-X) I don't know about the HTP374 because it hasn't yet been tested on our PowerMac-G4, but about other cards: - they perfectly work on the PowerMacG4 MDD - they perfectly work on our x86-box (intel core duo) - they randomly fail in the same way on the C3600 this might mean something. I Don't know. Anyway, even the I/O performance is not good on our C3600: none of the above move more than 20Mbyte/sec, while the internal SCSI moves 60Mbyte/sec. So I wonder if there is something really really wrong with the DMA: it's too slow!
