not good.

This is very useful information.

form the git log, the only thing that changed really was support for EFI.

Thats interesting. I wonder how that could be?

Could you try the vserver iso image too? It has a different kernel,
without the grsecurity patches. The syslinux.cfg is broken so you'd
need enter 'vserver' at the boot prompt where it complains about
missing grsec.

I dont think those causes any problems.

I have seen the address collision messages several places but it has
never caused any probles for me (that i am aware of at least)

The ones that panic would be interesting to see. Not sure how much i
can help there though.
