Hi James, hi all,
James, your recent 2.6.9-pre changes seem to cause new regressions in
the sym53c8xx_2 driver.
On my U30 sparc64 box I get many errors in the system log:

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,
