[Bug 1250321] Re: Ubuntu 13.10 + 14.04 Catastrophic Random Kernel Crashes on Boot with ASUS Sabertooth 990FX


There are some screenshots. I can't get any output from a regular boot
since my monitor then says 'No Display' so I have to use recovery mode
to show the error messages. I reinstalled Ubuntu 14.04 and set those
boot options; and as usual the first time I boot into Ubuntu 13.10/14.04
it works fine. Then when I reboot the screen goes black and shows blue
vertical lines with white horizontal rectangles and will never boot

  Ubuntu 13.10 + 14.04 Catastrophic Random Kernel Crashes on Boot with
  ASUS Sabertooth 990FX

Status in “linux-firmware” package in Ubuntu:

Bug description:
  System Specs:

  ASUS Sabertooth 990FX (with the latest BIOS)
  AMD FX-8120
  AMD Radeon HD 7950
  240GB Seagate SSD (20GiB / partition)
  2TB WD HDD (/home)

  I have installed Ubuntu 14.04 three times and each met the same fate.
  The first time you boot into the system after installing it, it works fine. However, after you install your usual programs like Steam, Skype, smplayer, etc. and reboot the system will fail on such a grand catastrophic scale that you can't even boot into recovery mode since that will begin spamming error messages quickly as well.

  It isn't related to the kernel because I used the same kernel in
  Ubuntu 13.04. I also had the same problems with Ubuntu 13.10 (I'm not
  sure if that still applies but I will soon find out).

  Meanwhile, Ubuntu 13.04 with kernel 3.12 works perfectly.
