acpi: suspend request ignored (not ready yet)

[RC]

I'm having problems with an intermittent bug (always the worst) on
FreeBSD 7.0.  About every 2nd or 3rd time I resume after suspending
(running acpiconf -s 3 in an xterm, or via an entry in blackbox's menu),
the xconsole and dmseg shows "acpi: suspend request ignored (not ready
yet)".  No other notable messages in any system logs. When that happens,
future invocations of acpiconf/zzz will silently exit.

It happens without ANY kernel modules (besides ACPI) loaded.  But it
seems to happen only under X11.  If I switch to a tty, and exec
acpiconf, it doesn't have any such problem (at least so far).

Hardware is: 
MSI KM2M Combo-L motherboard.
PCI NVidia 4mx 420 PCI card (NV driver)
Linksys LNE100 (Tulip) NIC

FreeBSD 6.2 acpi s3 worked great, with two minor exceptions:
-  Built-in (mobo) NIC driver fails after resume. 
-  X11 intermittently failed to switch to tty0, which caused video to
not reinit properly.  Switching to tty0 first worked flawlessly.


Additionally: rc.suspend doesn't seem to be getting invoked at all
(while it was with 6.2).  Yet rc.resume still is.  Again, no messages in
any system logs.  Am I missing something?
