Darn, I hadn't thought of that. Yes tty-revamp might be the culprit. Which serial driver are you using? Just 8250? For you convenience, http://www.zip.com.au/~akpm/linux/patches/stuff/2615mm2-no-tty-revamp.bz2 is 2.6.15-mm2 with just the tty-revamp and isicom patches reverted. - 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/ | ||||||||||||
