 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.
