Random crashes on snooze

I know I don't contribute much here but I just can't seem to find any clue
about what is happening.  So I need help.

I just upgraded to Yellow Dog 3.0.  Since doing so I have experienced seemingly
random crashes when I issue a "snooze" command "/sbin/snooze".

Here are machine specs:

I put some debug messages in the sleep code and I think it might have something
to do with the awacs sound driver.

>From /var/log/messages on a bad sleep:

But I don't know if there is something missing from the file because of course
nothing can be written to the disk at this time...  Does anyone have any other
