Here's /var/log/messages starting with the initial boot and through the
suspend and resume.  ACPI_DEBUG is enabled, but not bootverbose.

BTW, it also locks up when I switch back to X11 after resume.  Seems to
be related to the irq 11 storm.  Irq 11 is used by uhci0, fwohci0, fxp0,
and drm0.  The the top part of the display is corrupted after I switch
back, and the machine locks and blanks the screen within a few seconds.
I don't get the message about the irq 11 storm and the machine stays up
if I leave the console switched to a text vty.

This is the first time I've played with suspend and resume in a few
months.  It has never worked correctly.
