I have re-added the missing 4 lines to ept_update_paging_mode_cr0 in
vmx.c, which resolves this issue for in Kernel 2.6,37 and 2.6.39.
I haven't tested all guests, but neither Squeeze nor 2008 R2 reboot anymore.
Hmm, not 100% sure, but the issue might be that the arch.cr3 value does
not make it into the vmcs after cr3 was changed from user-space? This
would also be fixed with the change above.
So, basically, Linus just has to re-pull, since the
"change" I made is already in the tree. Or is there another way to solve
this? I find it hard to believe that I am the only one using
save/restore on Nehalem CPUs or that this bug only affects me.
Although I can verify this on dozens of machines.
Markus,
Please check whether the following patch fixes the problem for you.
Thanks, I will try that. But I won't be able to get back to you before
next week (short week in Germany *g*)
Markus
