Hi,

I am now working on a board with ADM5120 processor and want a kernel newer than 2.4.18, so I tried the linux-2.4.31-adm.diff.bz2 patch against vanilla 2.4.31 (http://www.linux-mips.org/wiki/ADMtek#Linux_2.4) but failed to compile it with PCI Bus support (It compiles OK without CONFIG_PCI). The compile error looks like this:

......

Is PCI Bus supported by this patch? Or, is there any new kernel availible for ADM5120?

Thanks very much.
