Try requesting the suspend using "apm --suspend" rather than
"tpctl --suspend" or a function key.  These work differently,
as I explain in the Power management section of my web page.

If you have "cardctl eject" in an apm proxy script, put a "sleep 2"
after it so that the ejection wins the race with apmd_proxy.
Here is my /etc/apm/event.d/pcmcia script:

#!/bin/sh
case "$1,$2" in
        suspend,*) cardctl eject ; sleep 2 ;;
esac

Note that nothing needs to be done on resume.  Cardmgr will detect
the card again on resume and "insert" it without any prompting.

Interesting.  This is another thing that could inhibit suspends.

Strange.
