The system has problems writing even the partition table to the disk. The write falls over with the following on VTY2: ahc_scsi_cmd0: more than 256 DMA segs sd0: oops not queued biodone: buffer already done init died (signal 0, exit 1) I have been occasionally to get past the partition write, but it mentions it can't mount swap and then fails to make the filesystems. This also happens with an IBM DFHS S2F 2Gb FAST SCSI-2 drive. It happens with a 1542C, 1542CF, AHA 2940 controller and on two different machines 100MHz Pentium and non PCI DX2 66MHz. Same problem, but different number of DMA segs on the 1542 (less SCB's??.) With a DEC DSP5200S 2Gb SCSI-2 (not FAST) I have no problems at all on either machine with any SCSI adapter. I'd really like a FAST drive though. Any ideas what this could be? TIA -- Mark Powell - Senior Network Technician - Room: C806 Computer Services Unit, University College Salford, Salford, UK.
