The address space collision is likely the cause of this HPMC.
(0xff6292 == HPMC)
With HPMC's, "PIM" info is worth collecting. See
http://www.parisc-linux.org/faq/kernelbug-howto.html
for details on how to collect PIM info.
It would also be helpful to collect "in io" output from the same PDC
prompt that allows one to run "ser pim" and "clearpim".
Lastly, if an older kernel does boot, "lspci -v" would be helpful.

The "parenting" of resources in the generic PCI support has been changed.
I can't say if it fixes this problem. Is it possible to test a 2.6.30
or 2.6.31-rc kernel?
thanks,
grant
