Re: [BLUG] power off CD?

You say "powers down", you mean the computers power turns off right,
not Ubuntu goes through the whole shutdown sequence?

That's an interesting problem, could it be that you've hit the maximum
power your power supply can handle? Maybe the CD was unreadable by
Linux and it spun the drive faster drawing more power? What type of
files are in the CD and how big are they?

Searching for inserting cd shuts off computer on google yeilds a
surprising number of results, but they are all windows problems, which
isn't surprising.
