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 -steve
