Hi Jan / David,
On the other thread you asked about some messages in xl-dmesg, over time
there are more that come from a kernel booting. (mind you that there can
be some changes in Kconfigs between the kernels i have used.)
3.16 was clean this is what xl-dmesg gained on log message that seem to
be triggered by something in the dom0 Kernel booting on my AMD system.
from 3.16 to 3.19 we gained a lot of these, if i remember correctly
related to
perf being enabled in the kernel:
+ traps.c:2655:d0v0 Domain attempted WRMSR 00000000c0000081 from
0xe023e00800000000 to 0x0023001000000000.

from 3.19 to 4.0 we gained:
+ d0 attempted to change d0v0's CR4 flags 00000660 -> 00000760
+ d0 attempted to change d0v1's CR4 flags 00000660 -> 00000760

+ d0 attempted to change d0v5's CR4 flags 00000660 -> 00000760
and from 4.0 to 4.1 we gained the ones you were interested in:
+ traps.c:3227: GPF (0000): ffff82d080194a4d -> ffff82d080239d85
