Are you running 'xend'? The current console implementation is blocking, and hence you could stall after filling up the buffer if you haven't run the daemon to read it out.

Yes, xend is running. For now, I've hacked printk to call good old HYPERVISOR_console_write, and skipped the call to register_console().

Odd. This is with a xenolinux built from the same repository, right?

I think using HYPERVISOR_console_write is probably best for what you're doing anyhow -- the new xend console stuff has yet to be integrated with suspend/resume yet, but this should be straightforward.
