Hey,
since 2.5.67-bk5. I have been unable to boot my laptop
tonight, I finally traced it back to
http://linux.bkbits.net:8080/linux-2.5/cset@1.1006
this changeset
more details on the problem can be found
http://bugzilla.mozilla.org/show_bug.cgi?id=677
there
and
http://bad-sports.com/~brett/bugreports/kernel/2.5.69-failboot/
there
the video card is a chips and tech 65545
i'd just like to know where to go from here, so that I can return to
booting with CONFIG_VIDEO_SELECT set
i'm not on fbdev-devel, so please just cc me to any response
thanks,
/ Brett

good work.

Possibly the card's VGA BIOS has 'issues' with that call.
Wasn't the EDID stuff getting backed out anyways ?

This is most likely the case. I just tested out the configuration he has
and it worked for me. I'm running vga=5 right now. For teh majority it
works but as usual there are some broken BIOS that cause issues.

Only in the VESA driver. Some people did have luck with the BIOS EDID info
so I like to keep the BIOS call in there.

That code runs way earlier than before we get to do any PCI quirks,
so fixing that one up could be interesting.

Or possibly..
It looks to me that the store_edid function is unconditionally calling
the READ EDID function without first having called the installation
check function. (Int 10h ax=4f15 bx=0)
Ralf Brown's interrupt list (which is pretty much definitive afaik)
also notes that for the READ EDID function, dx should be 0, we are
using 1. Is there a reason for this ?

On my system (G450 + Compaq MV600 + TV) this EDID call takes about
5 seconds (fortunately it does not die), so I'll be happy if I can config
this out - especially as matroxfb gives you DDC access from inside Linux.
