Question: MBP 15': Frequent kernel panics

Hi,

Can someone help me analyze the following issue?

ISSUE

Frequent Kernel Panic


MBP Config

Using 8GB of ram in one slot

The second slot is empty

=> Why? Because when using both slots MBP crashes all the time just in minutes after start.

I have performed all combinations to test if

a) any of the ram stick is damaged,

b) any of the slots is dammaged

My conclusion:

Both stick function ok

Both slots are ok


But, as i said, I can't use the 2 slots at the same time.


With one slot being used I still have 'sporadic" panic kernel issues like the one below:


Any ideas?

that panic occured in, and because of, DisplayLink software.

Your MacBook Pro 8,2 has direct Hardware support for an external display accelerated by the built-in GPU Hardware:


2nd Display Support: Dual/Mirroring 2nd Max. Resolution: 2560x1600



Details: The maximum resolution supported on an external display is 2560x1600.

there is no need for you to have DisplayLink running.
