p7h55m occasional kernel panics on boot. (10.7.2)

[DaveSmith]

Motherboard: P7H55-m SI (System Integrated)

Processor: Intel I5 760

GPU: PNY GTX 460 1GB

 

So I got Lion successfully installed a couple of months back, and the installation went fine. Every now and again, I used to have a kernel panic on boot, but could happily live with it, mostly by just sleeping the computer every night. However, I now have to use Windows more again, therefore more reboots needed. Recently, it takes 4 or 5 attempts for Lion to boot up successfully. The rest of the time, the system kernel panics with one of a selection of errors:

 

Kernel extensions in backtrace:

 

com.apple.iokit.iousbfamily

 

or

 

org.voodoohda.driver.VoodooHDA(2.7.3)

 

 

There is another error and these two errors do both have another extension listed below them, and I will add them to this post as and when they happen.

If anyone has a similar issue and resolved it or any suggestions then it would be greatly appreciated

thanks
