./cvscompile locally is ok. Also if I disable HT in BIOS, the machine survives the crash "./cvscompile"ing via nfs and the next "./cvscompile"s over nfs are ok. Also if I unmount / mount the nfs share again. So it always happens the first time calling this ./cvscompile via nfs. - 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/
