Wait a second, just for clarity: are you saying that BESL-capable controllers do not support the old HIRD mechanism and thus just break on non-BESL aware OSes? I would've assumed that they somehow notice if software doesn't write to the new register and automatically fall back to HIRD... it seems like a weird decision to break hardware backwards compatibility like that (after all, it would mean that Linux 3.10 and older would also break on LynxPoint systems right now). -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
