Re: [Xen-users] Xen 4.1.0 + stable-2.6.32.x kernel = crashes, hangs, reboots

[agent 8131 <agent.8131@xxxxxxxxxxxx>]

Still happening.  the last 2 times the Xen 4.1 system has hard locked 
after running for 4-6 hours.  My plan is to try Xen 4.0.1 instead.  It 
would be nice if someone would support Xen 4.1.
