RE: [Xen-ia64-devel] RE: Updating to xen-unstable... results inXenfreeze

["Magenheimer, Dan (HP Labs Fort Collins)" <dan.magenheimer@xxxxxx>]

I seem to be having some hg problems.  I successfully
pulled the -Intel tree but hg update seems to get stuck.
I finally had to interrupt it after 10 minutes because
I am working at home and need to leave for work.
I'll try again later, but anybody else seen this problem
and know how to fix it?

Dan
