Re: [Xen-devel] Crashing with Xen (Debian Wheezy) 4.1 (deb) and 4.4 (source)

[Derek Piper <dcpiper@xxxxxxxxxxx>]

        What version of kernel is recommended? I went for the latest in the 3.2 
line (3.2.52 at the time) since I didn't want to worry about other system 
dependencies messing anything up. I could probably go to the 3.4 line if 
that's a good thing?

        I will certainly try the debug line and report back after it dies again.
