Pkg xen devel - Jul 2017 - debian with xen upgraded from deb8 to deb9 on Dell Optiplex 780 crashed too Bug #866952

hi, 

i upgraded my testsystem running on a Dell Optiplex 780 fine for the last five
years from Debian 8 to Debian 9.
It also crashes on boot, after 
complaining abount an errer for the mcelog (-16)

afterwards my monitor is out of frequency 

was not able to run further tests right now.

Hi Bill, 

i run into to same problem on a Dell Optiplex 780. 
This was running with Debian and Xen since 2011 without any trouble on that box.
After upgrade to Debian 9, xen 4.8 wont start anymore. 
But i can start Debian 9 without xen on the box. 

I saw you are running on a Dell R610 with bios 6.4.0. This is the latest bios
for your box.
I am currently pretty sure, i'm not running the latest bios on my box. 
The question would be, what setting would be wrong, if it depends on bios. 

For testing i have some Dell T710, i will try this week to find out more. 
Unfortunatly i have already deleted Xen 4.4 from Debian 8 from my box. 

best regards 
Thomas
