Last time, I did absolutely nothing. System was idle
and it crashed just after the login. Now, I booted the
system again and this time, there is no reset. But,
performance of the system is very slow. Browser
(Mozilla Firefox) freezes a lot. Also, before applying
patches, when I used to disabe xsave it resulted in
same kind of performance issues. And the following
is still present in the log.

(XEN) traps.c:3290: GPF (0000): ffff82d0801c1cea -> ffff82d080252e5c
