..and why my CDrom drive in the Laptop is generating lots of those ugly fault

Then there are the hangs on boot after

acpi_ec0: <Embedded Controller: GPE 0x1b, ECDT> port 0x66,0x62 on acpi0

I have to boot 3 or 4 times until the boot gets over that point,
sometimes I must boot Windows Vista (which still resides on the other
disk of this Computer) and shut it down again before I can boot over
that point above.

Maybe I'm a Noob..and have not enough time to read all the Mailing
lists or Manuals ..but I want to have those problems fixed.
I need the Notebook for some real work (Embedded development) and
decided after many years of using FreeBSD to give Dragonfly a try.
Dragonfly with mate seems to do a good job..if it's finally bootet and
if one can ignore that error messages. Are the problems fixable?
Is anyone besides me interested to get them fixed? I'm the only one with
that kind of problems? Should I switch back to FreeBSD?

Regards,

Holm
