Thanks for forwarding this, James.  Rene, it would be useful for you
to submit bug reports to the maintainer directly, or even contact linux-scsi.
I don't have time to wade through the mountains of crap on linux-kernel.

When do these show up?  Are they at initialisation time or are they during
normal operation?  You report the dmesg from a 2.6.8 kernel, how does the
2.6.9-rc2 one differ?  Is the sym2 driver version 2.1.18j in both kernels?

And I'm not on any linux-* list, sorry. The next time I will write to 
linux-scsi directly.

Both, at initialization time _and_ normal operation.

The 2.6.9-rc2 dmesg does list the same devices - but with 
"sym0:0:0:phase change 6-7 ..." between the devices beeing detected.

I'll rebuild the kernel with the defective scsi driver (I reverted the 
changes to get a functional system ...) when I'm back in the office in 
some hours. The 2.6.9-rc2 does contain the domain validation changes, I 
will take a look if the patch in 2.6.9-rc2 does change the version 
string if this matters.

Have fun,
