The kernel comes back, but the screen is black.  Manually switching VT's
is possible, and if I type something I can see it on the screen, but
there is no response and the cursor does not blink.  It looks as if the
VT is not switched backed on resume, and userspace tasks are not
restarted.  Sysrq combinations apparently work, but produce no output.

Cheers,
