[Bug 1307105] Re: Kernel install fails due PAE checks
If the kernel is booted, then forcepae must have been supplied, and if
it is supplied then PAE should be flagged in cpuinfo. It looks like
this is only about copying forcepae across. See comment #8 for that.

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.
