problem with kfree

I am experiencing a problem while removing a module in that kfree is
reporting a bad object. Here are the details:
I am working on getting (E)ISA support working and I have now gotten down
to getting a particular driver working (3c509), which besides it swapping
bytes around on the ethernet packets, seems to be working ok. The problem
comes when I try to remove the module. Specifically, kfree is giving a
"bad obj" error when trying to free the memory allocated in init_etherdev.
It is failing on the "PageSlab(page)" check, which checks to see if the
PG_Slab flag is set, which it isn't. The page->flags field is
0x8000100 for this particular page, the flag for PageSlab is 0x200. Any
clues on what is going wrong? 2.2.10 (with arch/mips modifications)
Thanks,
Andrew
