That would probably be because power-management hardware has only recently
stopped churning like a dog's breakfast in a tumble-dryer.

There was a new "standards" for power management every year for like 3 or 4
years, and early adopters of each added their own bugs.

The hardware manufacturer provided work-arounds for their bugs to Redmond,
but meanwhile everyone else was scrabbling first to figure out how the
standards were supposed to work, and then how to work around the bugs in the
implementations of those standards.

If you're using new (non-tablet) hardware, things are much better, but if
you're using old hardware it will still sometimes be flaky, even if you're
using the latest Linux kernel.

If you are using tablet or other mobile hardware, welcome to the whole new
world of "if you don't do your power management exactly right, you screw
your battery life", where everyone outside Redmond is running to catch-up
yet again. :-(

It's like the bad old days of disk drives, using CHS addressing, and needing
separate drivers for MFM, IDE, ATA & SCSI; now at least a single driver can
handle all the common types (ATA, SATA & SCSI) and they all look much the
same anyway.

suspend/resume work?

PPS: has anyone else noticed how Angry Birds chews up your Android battery?
