dev-list,
Every 2.4 kernel that I've tried freezes my Cyrix MediaGX system at boot
up.
Typically the last messages displayed are:
Working around Cyrix MediaGX virtual DMA bugs
CPU: Cyrix Media GX Core/Bus Clock Stepping 02
Checking 'hlt' instruction
Occasionally, the "Checking 'hlt' instruction" is not displayed before
it freezes.
My system is a PowerSpec Model 1810 (no laughs please), my Phoenix BIOS
reports "Cyrix GX 3.2 180MHz".
I've compiled/installed numerous 2.2.x kernels w/o any trouble. The
Redhat 7.1 CDROM image freezes at boot. I've compiled the 2.4.4, 2.4.5,
& 2.4.6 kernels with various config settings, but they all freeze at
boot. I'm currently running redhat 7.0, so I've tried compiling with
gcc (gcc 2.96 20000731) & kgcc (egcs 1.1.2 release), no luck.
I'm willing to compile the 2.4.[<4} kernels or try any other
pre-compiled kernels is anyone has a suggestion.
Please CC: me on any response

For what it's worth, I use the Slackware 8.0 distribution, and have no
trouble running 2.4.[5-7] on my Cyrix MediaGX 233 MHz. Make sure MTTR is off
in your configuration, this has bit me in the *ss once...
