Re: [Xen-users] Xen 4.6 DomU crashes: domain_crash_sync called from entry.S: fault at ffff82d08022a01e create_bounce_frame+0x66/0x13a

[Maarten Coenaerts <maarten@xxxxxxx>]

Just had another reboot of the domU and now I have a kernel panic in  
the console log.
Is this a problem with unstable clocksource?
