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

[Steve Langasek]

The conclusion from the kernel team is already that it's not possible to
work around this bug; and shim is *definitely* not the place for such a
workaround to live because each revision of shim involves a round-trip
to Microsoft.  If anything's going to block the boot, it needs to be the
kernel itself.

Since this bug is already assigned to the release notes, it's already on
the release team radar AFAICS.  But in any case, our best firmware
people have already concluded there's nothing we can reasonably do here
and the firmware just needs to get fixed.

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.
