I replaced the SC200 (ncr810) with a Tekram DC-390F (ncr875) controler, after seing it recommended by Stefan and that company supporting FreeBSD sym0: <875> port 0x6900-0x69ff mem 0xe2000000-0xe2000fff,0xe2002000-0xe20020ff irq 11 at device 13.0 on pci0 sym0: Tekram NVRAM, ID 7, Fast-20, SE, parity checking da0 at sym0 bus 0 target 0 lun 0 da0: Fixed Direct Access SCSI-2 device da0: 20.000MB/s transfers (20.000MHz, offset 15), Tagged Queueing Enabled da0: 2068MB (4235629 512 byte sectors: 255H 63S/T 263C) da1 at sym0 bus 0 target 1 lun 0 da1: Fixed Direct Access SCSI-2 device da1: 40.000MB/s transfers (20.000MHz, offset 15, 16bit) da1: 4134MB (8467200 512 byte sectors: 255H 63S/T 527C) da2 at sym0 bus 0 target 2 lun 0 da2: Fixed Direct Access SCSI-2 device da2: 20.000MB/s transfers (20.000MHz, offset 15), Tagged Queueing Enabled da2: 2063MB (4226725 512 byte sectors: 255H 63S/T 263C) and now the system is stable again. I did a lot of simultaneous disk shuffling, audio playback, network access and accelerated OpenGL .. everything worked fine!
