Replying to [comment:27 ashish]:

enables command/event logging.
Couldn't the delay slow down transfers by causing a delay in TCP ACKs
coming from the host kernel? We'd be hitting the debugging in the driver
before incoming packets are passed to the TCP stack.
> There might be a possibility that adding debug prints (because of this
mask) causing small delay in command execution that might be preventing
any race happening with driver/fw interaction.
That makes sense too. I'll try harder to reproduce tomorrow.
