Note that this is unlikely to be a communications issue because then
we should see the TCC complaining of commands that fail with a bad
echo. In more detail: every command to the MCP is echoed and the TCC
compares the echo to what it sent. If data from the MCP to the TCC is
getting corrupted then command echo should also be corrupted.
It is also unlikely to be a TCC error because the TCC has not changed
(also, it would be a difficult bug to implement in the TCC).
Hence I believe this is an MCP bug.
