The above lines are way to wide.

I believe lines of kdmump.txt should also be 80 columns wide or less. > On ppc64, use "crashkernel=128M@32M". > > -- > 1.7.10.4 > > > _______________________________________________ > kexec mailing list > [email protected] > http://lists.infradead.org/mailman/listinfo/kexec > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
