Not sure if it's the same problem but with 3530 on 3.2 with sleep_timeout set, I usually get first char dropped (as expected) but sometimes I get corrupted char instead too. Corrupt char seems to almost always happen if I set cpufreq to powersave, on performace it's almost always ok, so maybe it's some timing problem, -- Gražvydas -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
