The networking code uses a pool of buffers called mbufs; mget obtains a free buffer. Locking for access to the buffer pool is done by calling splimp(), which is supposed to be higher than any network device can interrupt. I think that some serial boards interrupt at a higher priority than this, and -- since SLIP runs on serial lines -- you can get into trouble. You can either restrap your serial board to a lower priority, or -- if you're skillful with adb -- you can patch the splimp() code to be a higher mask.
