Total freeze switching X->fb (matrox)

Total freeze switching X->fb (matrox)

[legion]

I have this problem with linux 2.6 (2.4 was ok).
I hope this is the right place to report this, it may be related with
"drm" mga module..

The problem is: framebuffer (matroxfb) works fine, X (xfree 4.3 or Xorg
6.7) works fine, but sometimes when i hit "ctrl alt F1" for switching
on the console, the system freeze.
It's not only a xfree freeze: no SysRq reboot and no working network
(sshd is not responding). hard freeze.
This happen *sometimes* : i switch between X and console many times
during the day, the box freeze only 2-3 times a day.

I don't known where to go to find the problem, the only interesting
element i have is:

2.4:
kernel: [drm] AGP 0.99 Aperture @ 0xe0000000 64MB
kernel: [drm] Initialized mga 3.0.2 20010321 on minor 0
2.6:
kernel: [drm] Initialized mga 3.1.0 20021029 on minor 0
kernel: agpgart: Found an AGP 2.0 compliant device at 0000:00:00.0.
kernel: agpgart: Putting AGP V2 device at 0000:00:00.0 into 1x mode
kernel: agpgart: Putting AGP V2 device at 0000:02:00.0 into 1x mode

may the problem be related with the newer version of the module?

any idea?

my stuffs:

video card: Matrox G400 DH on nvidia nforce2 motherboard
kernel: vanilla 2.6.3+ (nforce2 agp/matrox drm/matroxfb support)
X server: Xfree 4.3.0 or Xorg r6.7 using "mga" driver

thanks.

 It also happens with Matrox G550 on VIA board.
All 2.6.x kernels. XFree86 4.3 and 4.4.

 And 1280x1024-16@60 do not work (in fb, X is fine) :-(

Same thing here with Asus P4-PE board.
No matroxfb here, so this doesn't seem to be the problem.
I guess it's more an issue with agpart/drm.

Add me to the list... Matrox G400, AMD Irongate chipset.
It never seems to happen when X shuts down on it's own or when it
just startet up, that is, when I switch from the login screen.

MfG, Ulrich

... as I already mentioned, I don't use the matroxfb module and
am still experiencing these freezes when switching to another vc.
Under these circumstances, a patch for matroxfb probably won't
fix the problem ;-)
