The 2.1.97 PCI changes cause my Intel PCI Premier LXII to run type
1 configuration even though the machine is PCI-II. It runs this way,
but _very_ poorly. Reversing the order of test in pci_check_direct()
dodges the problem.
I don't know if this is chipset errata or what, but thought I should
report it in case other folks may be having the same troubles.
Cheers,
-Mike
