[Bug 1307105] Re: Kernel install fails due PAE checks

 

Just put the forcepae option after the "--" entry on the installer
command line and it will be copied to the target system.  The "--" entry
defines the boundary between options which are specific to the installer
and ones that are copied to the target system.

Title:
  Kernel install fails due PAE checks

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  [TRIAGE NOTE]
  When a user boots Ubuntu Live/Install media with 'forcepae' option, the option should automatically be added to /etc/default/grub, or kernel upgrades will refuse to install when they do not see pae capability in cpuinfo.

  On Thinkpad T42 with Pentium M processor linux image upgrade fails with message "This kernel does not support a non-PAE CPU.". System was installed from  ubuntu-14.04-beta2-desktop-i386.iso with "forcepae" kernel option. After install, system works, but cannot be upgraded to laters kernel.
