[pxc] smp 2.4.x oops

[Chanop Silpa-Anan]

recent attemp to get pxc200-F on a smp-box piii using via apollo
chipset up and running with smp kernel 2.4.10-pre4.

I've got the following opps from serial console duing "insmod ./pxc.o"


found PXC200F: mem=0xdf101000, irq=10

console shuts up ...


I still have (presumably) interrupt sharing problem when using up-kernel
2.4.x with this box which has to be investigated furthur. The symtomp is
that reading from the device has never return.


I cannot downgrade to 2.2.x for this box unless I reinstall every
partition with other file system than xfs.

Has anyone tried smp / 2.4.x. 0.3.0-beta has some supports.
Unfortunately, I don't have other box handy at the moment.



cheers,
