BUG: soft lockup detected on CPU#0

I just got me a brand new HP Pavillion DV9000 series laptop. Today, all of a sudden it refused to boot. This message was shown on the console while booting:

BUG: soft lockup detected on CPU#0

After some Googling people mentioned this message after inserting a WiFi card. I did just the opposite, though. The message started to appear when I booted with my WiFi card disabled by means of the kill switch at the front. Re-enabling the WiFi card was the solution. If my WiFi is turned on when I boot, my laptop boots just fine!
