The system in question is a twin-CPU PII-400 with 256MB ECC memory and an on-board Adaptec 7890 controller with a Seagate Cheetah Ultra2-LW disk and a Yamaha CD-R 4260t CD-writer. (entire dmesg & config attached below) Source is 3.0-SNAP-980520 with the CAM patches from the same day. Problem 1: I can't get the performance I want out of the disk. Probing when booting shows: da0 at ahc0 bus 0 target 0 lun 0 da0: Fixed Direct Access SCSI2 device da0: Serial Number LJ01239200001840H6VQ da0: 6.600MB/s transfers , 16bit), Tagged Queueing Enabled da0: 8683MB (17783240 512 byte sectors: 64H 32S/T 8683C) However, running camcontrol -i after booting gives me: [root@habanero] /sys/i386/conf > camcontrol -i Fixed Direct Access SCSI2 device Serial Number LJ01239200001840H6VQ 80.0MB/s transfers (40.0MHz, offset 0, 16bit), Tagged Queueing Enabled which seems more reasonable (to me at least). Playing around with bonnie, dd, etc gives no more than 5.2 MB/s throughput. This is both with and without the CD-burner attached, so it is not the cause of the problem. I would be happy to try out any ideas you have. Problem 2: The CD-writer doesn't show up when booting. I am clueless on this one, and would appreciate any hints (including "you have forgotten to add option FOO, stupid!" :-) that may help us in getting it going.
