Howdy people, I have noticed some scsi peculiarities; my ncr53c810 claims that it does not support synchronous transfers, but AFAIK it does.
--clip--
From /proc/scsi/ncr53c8xx/0:
Chip NCR53C810a, device id 0x1, revision id 0x12 IO port address 0xe000, IRQ number 11 Using memory mapped IO at virtual address 0xc4800000 Synchronous period factor 25, max commands per lun 32
From log:
ncr53c810a-0-<4,*>: SYNC transfers not supported. --clip--
Aren't these controversial? Inside /proc I can see a sync period factor of 25, which should produce 10Mhz as sync frequency, which seems quite appropriate. Then again at driver init (at boot) the kernel claims that SYNC transfers are not supported.
Then another thing; I tried ide-scsi for my ATAPI cdrom and when 'probe all luns on scsi devices' was enabled, the cdrom got detected 8 times, on every possible lun. Now, it's easy to get around this by disabling the probe option, but what if I had a CD jukebox _and_ I wanted to use ide-scsi? It is probably harmless that the drive gets detected 8 times, but it is just annoying if it can be avoided. Boot parameters, anyone?
