shutdown mode works ok, that's why I think driver problem is not too
likely.

3.19 is broken. Some kind of strange 3.17 works ok.

(On an additional note, x60 fails to boot when "hot" halting at

"ACPI: All ACPI Tables successfully acquired"

That was happening before, but it is really annoying for debugging. As
you do two reboots, machine gets hot enough, and you have to wait to
cool it down. Any ideas what to do there?)

I tried no_console_suspend=1, but it still suspended the console.
