As many people know I followed an excellent article on how to get OSX to run on the bare-metal of a HP Elitebook 8440p. One thing that I started to notice over the last week or so of using it was that 3 or even 4 times out of 5, I’d get a kernel panic at boot time just after the Apple logo was about to disappear and be replaced by a grey screen immediately before the login prompt.
It was very annoying.
At first I thought it was the wireless USB dongle that I had installed, because I’m fairly sure that after installation, when I was using a wired-only network, I wasn’t getting these panics.
Sometimes on the second or third attempt, with the USB dongle removed, the laptop would boot properly.. and all would be well.
In the end, I read a few random links here and there, and decided that I would remove the VoodooHDA.kext. Just deleting it from it’s place in /System/Library/Extensions was all that I did. Next time I booted (still without the USB dongle installed) I had no kernel panic.
I’ve booted four times in a row over the last two days, and no kernel panic (touch wood!) So I think I’ve accidentally found the culprit.
