Q: help diagnosing kernel panics? 10.6.8 related

Hello,

have been having this problem since i first tried to install 10.6 a few years ago.

thought it might be an issue relating to hp scanning driver .kext.

thought it might be RAM.

ram tests fine.

removed everything related to hp, which might relate to the hp scanning driver issue.

thought it might be a faulty SL install disk, but worked out ok on a macbook.

it seems only to happen with 10.6 and up, as i get the same problem when i installed 10.7 and 10.8 on other harddrives.

10.5.8 worked fine, with no problems or kernel panics in all the years it has been running.

if you have some insight that might help, i would appreciate it.

thank you.

(this from another new snow leopard install)
