There is nothing wrong with the SATA driver - I am posting from
2.6.15-rc1 now.
The problem is that the scsi order changed.
With 2.6.14 and earlier, I got:
sda, sdb, sdc : harddisks connected to sym2 pci host adapter
sdd, sde : harddisks connected to mainboard SATA
sdf,sdg,sdh,sdi : the slots in my USB card reader
With 2.6.15-rc1 and later, I get:
sda,sdb,sdc,sdd: the slots in my USB card reader
sde, sdf, sdg: harddisks connected to the sym2 pci host adapter
sdh, sdi : harddisks connected to mainboard SATA
This kernel have all drivers compiled in - no modules.
So I have to ask - is this change (USB devices before
any other scsi disks) _intentional_ ?
I can of course change my fstab, but I can imagine this causing all
sorts of trouble for people who plug in the occational USB pendrive.
Now it will shift all other scsi devices. That didn't happen before.
Therefore, I hope this change of scsi order will be reverted. USB should
be last, because USB drives are the most likely to be transient.
While SATA and SCSI host adapters are the ones most likely to contain
root file systems. I will happily test any patches attempting to restore
the old behaviour.
I guess mounting by UUID is another way of fixing this? Please tell if
this change is intentional - it will making mounting scsi disks by device sort
of useless for anyone with USB though :-/
