Matrox FB problem in latest 2.4.21-rc1-BK

[Willy TARREAU <willy@w.ods.org>]

Hello,

I just compiled 2.4.21-rc1 + bk cset-1.1137, and now the Matrox framebuffer
always starts in 640x480 mode, whatever the mode I tell it. Moreover, fbset
returns "ioctl: FBIOPUT_VSCREENINFO: invalid argument". This is on a G400,
and still works correctly on 2.4.21-rc1, so the problem really is within the
latest BK changes. I don't understand, since this cset doesn't contain matrox
changes, and no FB changes except intel's !

This is on a dual Athlon-XP 1800, Asus A7M266-D, 512 MB RAM, G400 video card.

I will try to revert changes one by one, but by the time, here is my epurated
.config (# lines removed). I append "video=matrox:vesa:0x107" to the cmdline.

Cheers,
Willy
