Paul,
The backtrace you posted is identical to the problem fixed by the patch
that Josh pointed you to. The patch has been submitted to Jeff. I asked
Jeff two days ago if this could be pulled in for 2.6.19. I verified the
bug and the fix on my machine. As far as I know, John still has not tried
the actual patch pointed to above. Just to clarify, without this patch,
any monolithic kernel will not work on pseries, but modular kernels will
still work. If someone can reproduce any problem with the libata patch
above applied, please let me know.
Brian
