[Xen-ia64-devel] scp bug report

[Alex Williamson <alex.williamson@xxxxxx>]

   FYI, I get the below BUG_ON when I try to scp a file from dom0.  To
reproduce, from dom0, scp a file from a remote system (ex. scp
user@remote:~/file ./).  Looks like we're expecting IRQs to be enabled,
but they're not.  Anyone else seeing this?  Thanks,

        Alex
