Thanks, Dave.

This is an odd one. One of the changes in 1.233 was MFC'ed in 1.222.2.5,
but the second part, describes as:
Cosmetic change to suspend, dont call tsleep an extra time at exit.
has never been MFCed for some reason. I'm copying Søren in hoes that he
will MFC the remainder of 1.233.

It does allow my system to suspend just fine, but it now locks up with
the disk active on resume :-(

I'll have to try the patch Gleb posted to see if it fixes this one!
