I'm building XFree86 4.6+patches for a selection of computers with various
video chipsets.
The kernel is a 2.4.34.
I found that the patch 4.6.99.17-4.6.99.18.diff.bz2 breaks the i810 driver
for the Intel
graphic chipset on these two Dell computers :
- Dell Optiplex GX270 / i865G
- Dell Optiplex GX280 / i915G
But note that this computer works well : Dell Optiplex GX260 / i845G
The syndrome : as soon as X startx, the screen becomes dark and the text
consoles become unusable too
(but the system doesn't crash). I can see this in /var/log/XFree86.0.log
(this example is for the i915G) :
[...]
(--) Chipset 915G found
(II) resource ranges after xf86ClaimFixedResources() call:

(II) Found conflict at: 0x3bb

(II) resSize:
[0] -1 0 0x00000000 - 0xffffffff (0x0) IX[B]
(II) window fixed:
[0] -1 0 0x00000000 - 0x0000ffff (0x10000) IX[B]
and the log file stops here.
Moreover, I have the same graphic chipsets (i865G and i915G) on non-Dell
motherboards
(MSI or Intel motherboards) and they work perfectly here. So I suspect
that the problem comes from
the Dell BIOS. Dell BIOSes are mostly not configurable, as you may know,
and I didn't find a parameter
which could be related to the problem.
There are some pci-related files which are altered by the patch, the error
probably comes from there.
Please post the output from `scanpci -v -v` on one of the failing systems.
Thanks.
Marc.
