HP Pavilion dv9000t Core 2 Duo won't boot when wireless switch is disabled

[Nikhil Fernandes]

When I turn off the wireless using the hardware switch when running Windows and try to boot, I get an error message saying BUG: soft lockup detected on CPU#0!. This can be resolved by re-enabling the wireless switch.

The 18 month support period for Edgy Eft 6.10 has reached its end of life. As a result, we are closing the linux-source-2.6.17 Edgy Eft kernel task. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!
