Well, that may have been premature. We are seeing the RXUBR interrupt get stuck asserted on Zynq hardware, and I failed to realize the driver clears RXUBR already in macb_interrupt... Not enabling that interrupt keeps my system responsive, but it's not the correct solution to this issue. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
