About two months ago I sent this email to the Xen users lists
regarding a problem I was having losing some of my serial console
output on boot:


Unfortunately it got no replies.

I was just wondering and hoping if any developers could answer the
following questions:

- Should I open a bug regarding the loss of serial console output on
  boot, and;

- Is sync_console as bad an idea as the warning suggests it is?

I get all my serial console output if I use sync_console, but I
haven't really put the machines under heavy load and would rather
trade off truncated boot messages as opposed to performance under
