Bug Description
Hi,
Problem:
The machine becomes somewhat unresponsive during the process as its flooding dmesg and also attempting to
reset the controller from what it looks like.
Environment:
In my Dom0 machine, I copy disk images (DomUs) so I can rebuild various software environments. In this
particular instance, I was trying to attempting to overwrite an existing img with a pristine one (cp build.img build-johnny.img)
where the image is 10G. I'm running Ubuntu 8.0.4.1 on AMD64 box with an ICH9 controller using
a WDC WD2500AAJS-7 drive.
An excerpt of the messages:

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:
1) If you are comfortable installing packages on your own, the linux-image- 2.6.27- * package is currently available for you to install and test.
--or--
2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http:// www.ubuntu. com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.
Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'.
