System freezes or kernel panic occurs. Happens since I put a new SSD in my Acer 1810TZ Laptop.
SSD: http://www.samsung.com/de/consumer/memory-storage/ssd/under-500-gb/MZ-7TE250BW

Problem seems to be somewhere between Kernel, SSD, BIOS, SATA support.
Already have the latest BIOS for my Laptop. System got more stable since
I installed new Kernel (3.11 instead of 3.8) and use btrfs-Filesystem
now. But still several freezes per day, especcially while browsing
complicated (java?)-websites.
