I have today tried out the latest development kernel on an Intel
SC450NX - this is a 7+ year old machine running a 4 way Intel Xeon
Pentium III 55 Mhz CPU environment. The machine has 3 in-built SCSI bus
controllers - all Symbios. Chip sym53c896, device id 0xb, revision id 0x1 At PCI address 0000:01:03.0, IRQ 17 Min. period factor 10, Wide SCSI BUS Max. started commands 448, max. commands per LUN 64 Chip sym53c896, device id 0xb, revision id 0x1 At PCI address 0000:01:03.1, IRQ 18 Min. period factor 10, Wide SCSI BUS Max. started commands 448, max. commands per LUN 64 Chip sym53c810a, device id 0x1, revision id 0x23 At PCI address 0000:00:08.0, IRQ 19 Min. period factor 25, Narrow SCSI BUS Max. started commands 448, max. commands per LUN 64 The box currently has 2 * 73GB drives on SCSI Channel 1.

The current one is 2.6.22.9-91.fc7. However with the FC8 candidate kernel (and the corresponding FC7 one in the testing updates) the Symbios buses fail to initialise properly.
