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: <QUANTUM FIREBALL ST2.1S 0F0C> 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: <IBM DCAS-34330W S65A> 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: <IBM DORS-32160 WA6A> 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!

Marc
