Really? memtest86 <http://www,memtest86.com> did finish its run without errors? I'm sure they'd want to get their hands on the broken RAM...

Sure enough, if the kernel lives (mostly) in unaffected memory, and furthermore doesn't bang on it quite as hard as a compiler run does (the kernel only runs for a tiny fraction of the time). -- Dr. Horst H. von Brand User #22616 counter.li.org Departamento de Informatica Fono: +56 32 654431 Universidad Tecnica Federico Santa Maria +56 32 654239 Casilla 110-V, Valparaiso, Chile Fax: +56 32 797513 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
