RE: [iPAQ] More on mouting CFs

Rich,

Nice work!

It looks like the problem is due to the fact that there is no way for the suspend script in cardmgr to hold up the actual socket suspend until the cardmgr suspend script can complete.

Hmm. Actually, it looks like /etc/pcmcia/ide suspend does not do anything. From a quick glance at the various pieces, it really looks like the power to the ide device is shut off without any preparation. That can't be good.

You could try explicitly umounting the CF filesystems in a script in /etc/suspend-scripts -- and cardctl eject might not hurt either.
