The addresses 0x800cbfdc / 0x800cbfbc are not valid kernel addresses on
the Indy.  Is it possible you wrote them down wrong?  0x880cbfdc /
0x880cbfbc however would make sense and are indeed in the sgiseeq driver.
I'll take a closer look at it.

The message is correct.  The difference is because of a hole in the Indy's
address space comparable to the 640kb - 1024kb hole on PCs.

(This should go into the FAQ)

Are you shure?  Some peopple got fooled by the 1024 vs. 1024 bytes per
kb isue ...  Or are the numbers way off?

There is a command named ``hinv'' under IRIX.  Can you mail me the output?

I'm going to put binaries of 2.0.91 online.  That kernel seems to be
running very reliable for me.  In fact it's too reliable to debug, I can't
reproduce the one killer bug I know of it must be still there ...
