I was wondering why pnp depends on isa being selected in 2.6.2-rc2, is
pnp really only relevant to isa? What happens with pci etc. ?
This may explain why using pnpbios locks up my machine (at least as of 2.6.0-test9).

Yes, it only is related to isa devices, but they include onboard devices
such as serial ports. It will, however, prevent resource conflicts
between pci and system devices, especially with unusual configurations.
Does using pnpbios cause your machine to lockup at boot? If so, around
where does it occur? DMI information would also be useful for blacklisting
purposes.
Thanks,

I the 2.4.x kernel I seem to remember being able to cat /proc/isapnp
and getting info about pnp devices on my system. Is there an
equivalent in 2.6.x ?

Yes. A complete interface, including id information and control over
resource management is provided through sysfs.
#mkdir /sys
#mount -t sysfs none /sys
Look in /sys/bus/pnp for more information.

I just checked again with 2.6.2-rc2. It occurs right after pnpbios
starts up. I wrote the oops down by hand since the computer went into a
hard lockup (no sysrq key), but couldn't get any results out of
ksymoops for some reason (maybe I am misusing it, any way to disable
pnpbios on a kernel compiled with so I can run it from the running
kernel?).
I attached the oops log and the dmi data (didn't know what is needed of
it).

the kernel parameter pnpbios=off should work.

I appreciate the information will add this to the blacklist.
