Description Kristo Kriechbaum 2006-03-12 11:40:35 UTC

I have a Dell 700m with an i855GM chipset.  X crashes with a "Bad V_BIOS
checksum" warning followed by a "vm86() syscall generated signal 11." error when
I try to use a dual-head configuration.

Other configuration info:
Fedora Core 4
kernel 2.6.15-1.1833_FC4
xorg-x11 6.8.2-37.FC4.49.2

I don't know if this is a cause of the problem or not, but I use the
855resolution program (http://perso.wanadoo.fr/apoirier/) to add a 1280x800 mode
to the video bios.

I found related bugs, but none with this exact problem.

This bug sounds very similar to #3105. You should try my test driver for 6.8.2
that's available here.

Excellent!

i810_drv.o from the link you provided fixes this problem.  I didn't do alot of
testing, but everything seems to work fine, even coming back from suspend to ram
it still works.  The dual-head display works with the xorg.conf file I attached
(using the multihead layout of course).

I can try specific tests if that would help, else I would consider this fixed...

As I mentioned, the driver on your website fixed this problem.  But the most
recent xorg update (in FC4) breaks things again.

I tried to get the updated driver from your website, but I get a 404 error.  I
realize this is probably a Fedora problem, but before i complain to them again I
want to make sure.
