Comment 5 for bug 891078

No, it's a usb attached board issue, of which snowball is the only one we have that requires a usb connection at the moment. :)
Did you see my email though? I've worked around this at the moment by just calling cu in a loop from conmux. Unless you see a downside to this, the upside is that it also fixes the issue we have with not being able to cache the first several seconds of boot when, and having to work around that for snowaball boards in lava-dispatcher.

However, for completeness, if this is a bug in libio-multiplex-perl, you should consider filing a bug against that and how you see it as a general problem, not just a problem for our case.
