Turns out another user reported the same issue with a slightly different model: https://github.com/networkupstools/nut/issues/231 <https://github.com/networkupstools/nut/issues/231> The "stty -f /dev/cuaU0 raw" trick should help, but I am confused as to why FreeBSD has different "raw" settings than what is set up at the same time as the baud rate:

Patrick, there following patches fix xenpaging for me. Granttable handling is incomplete. If a page is gone, a GNTST_eagain should be returned to the caller to inidcate the hypercall has to be retried after a while, until the page is available again. Please review.

Hi Keir: These two patches remove the need for netloop by performing the copying in netback and only if it is necessary. The rationale is that most packets will be processed without delay allowing them to be freed without copying at all. So instead of copying every packet destined to dom0 we''ll only copy those that linger longer than a specified amount of time (currently 0.5s). As it
