PROBLEM: 2.4.9 bootup oops on kmalloc

Short Descr: Oops on kmalloc
Long Descr: Kernel crashes with an oops on loading of rc/rcS/any other init
loadup, however with a precompiled kernel from Debian I do not suffer this
problem. (Old box never had any problem, new box does). Complains of kmalloc,
dies randomly on init processes with errors that aren't always the same.
Sysem is a 1.33ghz T-Bird on a KK266 w/ 2x512mb DIMM's @133mhz. Highmem is
turned on.
Area of problem: kmalloc
Kernel Version: Linux 2.4.9
