Re: fonts corruption with 3dfx drm module

[Christian Burger <christian.burger@edb.ericsson.se>]

I've seen a much more serious problem which seems to be related to this:
I have AMD Athlon K7 650MHz, Via chipset, Voodoo5 5500AGP, MTTR enabled.
What is happening here is that when switching back from init 5 to init 3 for
instance, the system hangs completely and a blinking character appears in a
black screen. There's no other way other than to power cycle the system. It
seems to be a kernel panic.
Kernel version is 2.4.18, and it happens with or without DRM support, with and
without FB support. There's no way I can have this version of the kernel to work
here.
Thanks, 

	Christian Burger

MTRR, of course (do you like 2D and even 3D hardware accelerated without 
MTRR?), FB, no, chipset is a AMD 750 (Irongate C4), using X 4.1.99.1 DRI CVS.

I am with the DRI devel team and saw it occasionally with XFree86 DRI CVS 
trunk and the latest mesa-4-0-branch. At that time I had FB enabled as I 
remember right.

The current DRI stuff is "only" missing the latest XFree86 4.2.0 release 2D 
code. Update is under way.

I can _NOT_ see it without FB and currently running 
2.4.18-pre7-J6-VM-23-preempt-lock.
