generating greio events in ARM Linux

Hi,

I'm attempting to port our application from QNX to Linux (beaglebone black) and I've run into an issue.  It seems my application is not generating any greio events.  I've tried our app as well as the Thermostat IO app.  The thermostat app will not generate any output events our run any of the lua scripts.  I think the input device is configured correcty, as I see these events:

EVENT [361.594]:IO: Dispatch [gre.press]
EVENT [361.594]:IO: Queue [0] gre.press
EVENT [361.665]:IO: Dispatch [gre.release]
EVENT [361.665]:IO: Queue [0] gre.release

when I run the apps on Windows, I see this in the debug output 

EVENT [44.357]:IO: Queue [1] gre.press
EVENT [44.357]:IO: Dispatch [gre.press]
EVENT [45.452]:IO: Queue [1] gre.release
EVENT [45.452]:IO: Dispatch [gre.release]
ACTION [45.452]:ACTION: Invoke [gre.release]->[gra.greio] on control [btn_utilities]
ERROR [45.453]:Can't open greio channel [VIC_controller] 2

on the Linux platform, no ACTION items appear. the same output occurs on the Thermostat example app.

I can send GREIO events to my application, both through our code and with the iogen program, so it seems the messaging is working (SysV messaging according to the manual)

Running as root has the same effect.

I also tried this command line switch:  -ogreio,queue, with no effect.

The command line I'm using and all debug output is here:
