FYI.
I wanted to test CONFIG_SMP stuff on a 32-bit capable box and was
given access to a J6000 (thanks rick!). The box has PDC rev 4.9 and
consistently HPMC's on the first PCI configuration space access.
C3k and J5k don't HPMC with kernels built from the same source.
I know c3k works and I'm sure jsm would let me know if j5k didn't.
I built the vanilla 32-bit kernel from source from today's CVS.
I'm not going to pursue this right now.
If anyone from TCD is concerned about this, I need ideas on why j5k
and A500 (PAT PDC) would work and j6k would not. I already know
parisc-linux does not touch the DMA hint registers. But that
shouldn't be relevant at this point.
Full console output is appended.
later,
