System is a DEC Alpha 433au with two SCSI disks.  SCSI controller is a
QLA1040 supported by the qla1280 driver.  Runs 2.6.16 fine.  Tried
booting 2.6.17-rc1 and got

kobject_add failed for 0:0: with -EEXIST, don't try to register things with the same name in the same directory

and a fairly long trace output when the system attempted to add sdb.
Not surprisingly, sdb was inaccessible.

Normally (for 2.6.16 anyway), the following relationship exists:

sd 0:0:0:0	sda
sd 0:0:1:0	sdb

More information *might* be available if needed, but will have to be
transcribed by hand.  My /usr partition is on sdb, so I don't get very
far with 2.6.17-rc1 on Alpha :-).  The problem is probably specific to
the qla1280 or the Alpha, as I have a x86 Adaptec SCSI-based system
with multiple spindles that works fine with 2.6.17-rc1.

See my post on 4/21:

	"2.6.17-rc2: kobject_add failed"

Perhaps this is related?

My "kobject_add failed" issue with 2.6.17-rc1 and -rc2 was a previously
undiscovered code error in the Alpha-specific strncpy() routine.  See
http://marc.theaimsgroup.com/?t=114555387000005&r=1&w=2
for the gory details.  Ivan Kokshaysky provided the fix, which I hope
has been captured for inclusion in -rc3.

I don't have Ivan's strncpy() fix and I don't think it's in mainline either.

Ivan, pelase send it over when it's ready?
