Re: [Xen-devel] copying large files over NFS locks up machine on-testing from Thursday

[Kip Macy <kip.macy@xxxxxxxxx>]

No bridge helps with NFS, but I just tried scp on a freshly re-booted
machine and it locked up instantly. Booting into Centos4 SMP and the
scp works fine - if this a SUE it is a particularly inventive one.

I guess it is time to move to the server room and cross my fingers
that this is a 100Mbit issue.
