<pre>sigh ... don't know how this got fouled up - this sentence
the only difference with this kernel command option (radeon.dpm=0) is that the
messages do not appear; the symptoms stay - the black xorg TTY, killing X from
another TTY.
should be attached to this section:
when this started one thing I tried was changing the kernel command line
GRUB_CMDLINE_LINUX_DEFAULT=" md_mod.start_ro=1 radeon.audio=1 radeon.dpm=0 "</pre>
