As you will see in the attached file (it's a dmesg from the boot)
I have an 1Ghz athlon cpu with a VIA KT133 on a gigabyte GA-7ZX 
motherboard with 100mhz SDRAM.When I compiled the kernel with 
cputype=Athlon I continiusly experienced this crash.When I compiled with 
cputype=i686 everything went smooth (OS is Redhat 7.1)
