Just exactly how thorough is the memory testing on that CD? When I run it memory tests pass ok. My Apple technician says that it's a faulty logic board but he doesn't have any proof other than he cannot find anything else that would be causing this problem. As I'm in Thailand overheating could be an issue. Most panics are Data Access type errors usually with the same backtrace infomration but there's no symbols in the backtrace so I'm lost as to here to start. I had been running my Tibook onm it's AC adaptor a lot recently. I'm told it gets hotter than if you are running on battery. I have seen the problem recently with a clean 10.2 10.2.1 and 10.2.2 installation. On Wed, 4 Dec 2002, William Kucharski wrote:

Robert,

The wide variety of panics you're seeing (some instruction miss, some data)

make me believe there is memory corruption of some type going on, which makes

me suspect the RAM in your TiBook may be acting up (or is overheating.)

Specifically the last trap you received - the Unexpected user state trap of

0x401 - should never occur.

A reinstall of 10.2.2 couldn't hurt but you may want to run your Hardware Test

CD first just to see if it has any RAM complaints...
