hard freeze on shut down

[evgen]

I have an issue on samsung r70 laptop [Ubuntu 9.04 (Jaunty Jackalope)], that after the "shut down" button is pressed, everything seems to work correctly (short kernel messages with....[ok] at the end of the line; ubuntu logo appears;), but then laptop just hangs, that power and wirelesslan led's are on, and the wild colors do appear on the screen...

The laptop does not react, and can only be turned off by pressing and holding the "start up"-button.

This issue was not present in Ubuntu 8.04/8.10 (hardy or intrepid).

Thank you for taking the time to report this bug and helping to make Ubuntu better.
Unfortunately, we can't fix it because your description didn't include enough information.

Next time this happens, if possible, can you switch to a text console by hitting
CTRL + ALT + F1, login there, and then run
sudo apport-collect 370273

This will gather a lot of debugging information related to your issue.
To run apport-collect you may need to install the package python-launchpadlib
(apt-get install pythonplaunchpadlib)

Thanks in advance

as i mentioned it is a hard freeze, so there is not way to do something, because keyboard and screen are locked!

so no ctrl-alt-f1 possible!

also these freezes appear randomly!

and crazy colors on the screen every time...
