howzit folks?
i’m trying to figure out why mtrr is causing the kernel to dump but googling has found nothing i can use to get to the root of the problem.
here is part of the output from /var/log/warn

please let me know if you need any additional output or where i should look to sort this out.
btw this started happening 27th october, i assume after i updated the system (or installed software). is there a simple way to see what was installed/updated via zypper at a specific date and time?
cheers
