Hello,

I hope you can help me with the following problem.
One of my systems got some bigger problems, it stops and/or reboots every few days.
Today I was able to make a screenshot of the kernel oops, it's attached to this email. Because I made it via a digital photography and typing it in again it's possible that there are typos in it but I hope everything is fine.

Please send this photo and config file.

Remarks: It's a new system - I'm unsure if possibly unreliable hardware also can cause Oopses or if Ooopses everytime are caused by errors in the kernel itself. If it's caused by the hardware - is there a chance to get a hint by the oops pointing to the components causing the errors?

There are some hints about hardware testing in chapter 6

Thank you very much in advance!
