Sorry, but the Papercuts Ninjas address papercuts
<https://wiki.ubuntu.com/One%20Hundred%20Papercuts/Papercuts>. Because
the bug affects the Linux kernel, it isn't a papercut!

HI,
i have been pointed to this team - maybe you want to have a look at
https://bugs.launchpad.net/baltix/+bug/930447
i have made a simple patch as a workaround - it`s here:
https://bugs.launchpad.net/baltix/+bug/930447/comments/224
it was never meant for mainline (and - no wonder - has been rejected there),
but i´m curious why it`s a no-go to add it to the ubuntu-kernel to fix issues
affecting hundreds of users which result from the decision to drop non-pae
kernel support.
the patch does something, grub bootloader does anyway:
skipping cpu check at early boot. (yes, grub2.x enters the kernel at a later
stage and skips vga initalization and cpu check - this is why fake-pae from
bernd-kreuss is possible at all !!)
the issue with ubuntu is, that sys/isolinux bootloader (on install-cd) does NOT skip the
cpu check on early boot and the other issue is, that the "pae" flag is missing
in /proc/cpuinfo - kernel package install routines are checking for it.
so, the patch does nothing but letting a user manually override the cpu
checking routine on early boot and adding a fake entry for pae in
/proc/cpuinfo, so the kernel will boot and kernel package updates will not fail
anymore.
the patch does nothing but empowering the user to tell his system "linux, please
boot, regardless what the cpu is telling you about PAE support...."
regards
roland
