[Bug 1040557] Re: UEFI boot live-usb bricks SAMSUNG 530U3C, np700z5c laptop

[Steve Langasek]

Samsung has suggested that this issue is being triggered by the samsung-
laptop kernel module.  This module is known to cause other issues on
Samsung systems when booted in EFI mode:

Kernel team: is it possible to disable the samsung-laptop module when
booted under EFI mode?  Obviously this would have to be done at module
load time; but that may be the best workaround until upstream is able to
fix the module to stop tickling the firmware bug.  I would prefer for us
not to have to disable the samsung-laptop module entirely to work around
this, since that would cause regressions for users who have Ubuntu
working fine on their systems already in BIOS mode.

Bug description:
  I cannot provide detailed log massages because laptop is bricked right
  now.

  If you have courage to try it select UEFI boot from bios and than try
  to boot laptop using liveusb (made form Precise Pangolin 12.04.1
  amd64).

  Laptop hangs up in black screen. If you force power-off, after it,
  laptop wont start. I mean it not event start bios, just black screen
  no sounds nothing.

  I filing this report, because i already bricked second laptop. At
  first i thought it was unrelated issue and laptop was fixed by
  warranty service (replaced motherboard), but after second time i quite
  sure.
