Which exact hardware is that, look for the skge line in the kernel log (dmesg)? I am not a hardware wizard, but I wrote that comment. My guess is that it shows up when the hardware decides to clock in some data that isn't really a packet (line noise, etc). Both skge and sk98lin just clear the error and keep going. Does it happen a lot or just once? - 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/
