Hi all!

I currently try to debug why the sisfb driver crashes my machine. (SIS 630
based laptop - linux-2.4.5-ac13).

On my serial-console I get:
sisfb: framebuffer at 0xe0000000, mapped to 0xcb800000, size 16384k
sisfb: MMIO at 0xefce0000, mapped to 0xcc801000, size 128k
sisfb: encountered LCD # debug output by me
sisfb: fall back to 1024x768 # debug ouput by me
sisfb: LCD mode # debug output by me
sisfb: mode is 800x600x8, linelength=800
Unable to handle kernel paging request at virtual address cc800180

This happens in the method: register_framebuffer called from sisfb_init.

I compared the sisfb_init with other framebuffer drivers and can't find what is wrong.
(I normally don't do kernel hacking...). What does the kernel try to do with the
_io-memory_, mapped around line 2230 in sis_main.c? - Must the memory reqeuested or
mapped in an other way?

Another strange thing is, that the code seems to work for some people ...

I would be nice if anyone could give me a hint - because the sis-drivers (kernel and X)
doesn't work for many people ...
