Возникает ошибка AIS(TPSS) при тяжелой нагрузке.
Вот некое
описание ядра MAC, и там есть список причин, по которым срабатывает TPS:

The transmit process remains running, until one of the following events occurs:
• The hardware or software reset is issued. Setting the CSR0.0 (SWR) bit can perform the software reset.
After the reset, all the internal registers return to their default states. The current descriptor's position in
the transmit descriptor list is lost.
• A stop transmit command is issued by the host. This can be performed by writing 0 to the
CSR6.13 (ST) bit. The current descriptor's position is retained.
• The descriptor owned by the host is found. The current descriptor's position is retained.
• The transmit FIFO underflow error is detected. An underflow error is generated when the transmit FIFO is
empty during the transmission of the frame. When it occurs, the transmit process enters a suspended
state. Transmit automatic polling is internally disabled, even if it is enabled by the host by writing the TAP
bits. The current descriptor's position is retained.
Вот и посмотрите, может быть, у вас одно из этих событий происходит.
