Not much actually - perhaps I need to enable some debugging:

More EH occurs - I've left it for ~5 mins, but let me know if longer would give more information, eg if it converges on a lower speed.
Would it be useful to compare some of the port setup registers in the working and non-working cases? Or any other debug I can grab? -- Daniel J Blueman - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
