(Bah, even a zombie can type ccache -C; make -j8 and stare...)

kbuild again hung on the first go (yay), and post hang data written to
sdd1 survived (kernel source lives in sdb3). Full ftrace buffer (echo
1 > events/block/enable) available off list if desired. dmesg.txt.xz
is dmesg from post hang crashdump, attached because it contains the
tail of trace buffer, so _might_ be useful.
