This will always happen as the clocks get reset and the signal needs to be
resynced.

Not necessarily.  There are many pins associated with hdmi.  You may be
able to generate a signal that works, but the linux connection relies on
being able to read the EDID information from the television as well.
 Without logs we can only guess what is going on.

The B1's have flaky hdmi connectivity at best.  Not only were there jack
location problems that needed to be addressed, but they were susceptible to
ESD causing a failure in the hot-plug detection circuit.  These are both
reasons why HDMI would fail to work  under Linux.
