I believe I am having instability problems with X (the system just hums along
in runlevel 3 without X running). I have a Tyan S4266 MPX mobo (most recent
BIOS version) with two Athlon XP1600+ cpu's and a Matrox G450 dual-head video
card. I have updated the video BIOS to the most recent version and am using
the current Matrox-supplied X11 drivers. My XFree86 is version 4.2.0-10mdk
(what comes with Mandrake 8.2).
I have an syslog message that tells me:
kernel: mtrr: detected mtrr type: Intel
kernel: mtrr: your CPUs had inconsistent fixed MTRR settings
kernel: mtrr: probably your BIOS does not setup all CPUs
kernel: mtrr: base(0xea000000) is not aligned on a size(0x1800000) boundary
kernel: mtrr: base(0xea000000) is not aligned on a size(0x1800000) boundary
kernel: mtrr: base(0xea000000) is not aligned on a size(0x1800000) boundary
The X11 log tells me:

In XF86Config-4, AGP is set to "1".
So after some mail list archive searching, I have inserted mem=nopentium in
LILO and X is more stable, but it still crashes (although less frequently)
and occasionally locks up the system completely (no ssh in, no vt; no
Atl-Ctrl-Backspace, no Alt-Ctrl-Delete -- Alt- SysRq-B will reboot as will
the hardware reset on the case -- thank goodness for reiserfs.
Will a newer version of XFree86 help? Is the version in cooker (4.2.0-20-mdk)
useable in 8.2?
Any advice would be appreciated.
