[Xen-users] dom0 panic after recent security patches

[marcotte@xxxxxxxxx (Brian Marcotte)]

I'm not sure if the following dom0 panic is a Xen problem, but I've
seen it frequently since the recent Xen security patches (XSA-185-187).

Before the patches, I had only seen it a couple times this year. Now,
some of my machines see it every few days.

Xen is 4.6.3, and Linux dom0 is 4.4.15 (also tried 4.4.20).

Has anyone else seen anything like this?

Thanks.
