No idea, but I did reference a website that posted this fix. I'm not
sure how the fix came about, or what discussions were done. The fix
seems to have been made by Ubuntu, which means its just another thing
they looked at without sending upstream :-p

Hmm, no_console_suspend on the kernel command line seems to do nothing.
It still hangs hard without the script, and suspend works fine with the
script.

I noticed that /sys/module/printk/parameters/console_suspend doesn't
exist. Am I missing a kernel config option?
