I've noticed this with the Intel 865G chipset (i810 driver) on XFree86
4.7.0
(Linux, 2.4.35 kernel).
I've got two different machines with this chipset. In both cases, the BIOS
is
set-up for using 8MB of VRAM (this memory is taken from the RAM).
1) industrial PC : 8085:2572 with subvendor/device 8086:4246 (Intel 865
GBF motherboard)
Here there is no crash.
2) Dell GX270 : 8086:2572 with subvendor/device 1028:0151 (Dell
motherboard)
Here X crashes when switching to text console and back to X.
It seems that the Dell BIOS mismanages something ...
The solution I found to avoid this crash is to use 865patch (available at
http://www.chzsoft.com.ar/855patch.html) and set the VRAM to 32000
(for example) before starting X.
I think this could be mentionned in the release-notes and/or i810 man
page.
IMHO the same information could be given for the Intel 845G (eg apply
845patch).
The driver already does this for some chips. Can you produce a patch to the
driver that extends this to other chip revisions? I have little experience
with this driver and no hardware that I could use to test such a change.
A little more digging reveals that the functionality of all the various
8x5patch utilities has already been integrated into the driver. At this
point, I think a log from both the functioning and non-functioning cases
would help.
Thanks.
Marc.
