I updated the Kernel to 3.13.0-34.60~precise1 and got the same freezes at startup. I found the kernel parameters "debug ignore_loglevel print_fatal_signals=1 LOGLEVEL=8 earlyprintk=vga,keep sched_debug" in Archlinux Wiki [1]. When i boot with these Parameters and "console=tty console=ttyS0,115200n8" for logging I get
[ 8.853449] [drm] Memory usable by graphics device = 2048M [ 8.853452] checking generic (e0000000 500000) vs hw (e0000000 10000000) [ 8.853453] fb: conflicting fb hw usage inteldrmfb vs VESA VGA - removing generic driver [ 9.220645] Console: switching to colour dummy device 80x25 I googled the Error and found [2]. Disabling the framebuffer with the parameter "video=vesafb:off" does not help. I get the same Error at normal startups, too.
