When the DMA engine state gets corrupted due to a hardware issues, it often won't stop rx until a full reset is issued. In that case the hardware must keep a valid descriptor, otherwise it will write to random places in system RAM, triggering random crashes. To fix this, keep a dummy descriptor without a buffer that keeps the DMA engine in a sane state until the reset is done SVN-Revision: 27895 |
