2.6.0-t1 garbage in /proc/ioports and oops

Hi, I am seeing some garbage data in /proc/ioports. Currently, I can cat
the file without an oops, but on a previous boot, the following oops came
up when catting the file.

Exact output from /proc/ioports is attached (some 8-bit garbage), as well as
lsmod output. Let me know if further data is needed.

I suspect that this is a problem in one of the drivers I am using, but
how do I track down which one it is (since the name is not there)?

Thanks,
-Chris
