My nice-but-cumbersome lapdog decided some time ago that being asked to suspend is insulting or something, and now goes catatonic instead: the suspend works fine, but absolutelly nothing, ever, wakes it up again.
"Roses are red and my SO-DIMMs still hot, you asked me to sleep but I'll let you rot."
A lot of debugging (and swearing) later, I now know that the
culprit (at least for kernel 18.104.22.168) is the module lpc_sch, which
isn't needed for normal operations anyway.
blam! Bye-bye, module.
