[Bug 1504744] Re: Kernel 3.2.0-91-generic "end trace" boot failure


Thanks for taking the time to report this bug and helping to make Ubuntu
better. We appreciate the difficulties you are facing, but this appears
to be a "regular" (non-security) bug.  I have unmarked it as a security
issue since this bug does not show evidence of allowing attackers to
cross privilege boundaries nor directly cause loss of data/privacy.

  Kernel 3.2.0-91-generic "end trace" boot failure

Status in linux package in Ubuntu:

Bug description:
  Hi All,

  On this computer we recently updated to the 3.2.0-91-generic version,
  but it failed to start with a list of errors. Always ending in
  something with "end trace".

  The computer uses:
  -- Description:	Ubuntu 12.04.5 LTS
  -- Release:	        12.04

  Depending on the devices and network cables the errors changed, but
  always failed to properly boot.

  Also we are not able to change the bootoptions of grub, because when
  pressing keyboard keys no responses where captured by the grub
  software. The only keys pressed that where processed by grub where
  just before the load of the grub bootoption screen.

  Work around:
  -- use Ubuntu boot cd/dvd and fire up a temp Ubuntu environment
  -- remove 3.2.0-91-generic components from boot folder
  -- copy previous version (in my case 3.2.0-90-generic) of the components to a 3.2.0-91-generic naming and Ubuntu starts up again fine

  Hope you can fix it soon, because more people are likely to get stuck!
  And may have not my inside knowledge
