Just FYI, the patch Yinghai mentioned above was experimental, and we decided it was the wrong solution. For 2.6.22, the easiest workaround is to boot with the "legacy_serial.force" option. For 2.6.23, we reverted my patch that caused the names to be swapped: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=57d4810ea0d9ca58a7bcc1336607f0cede0a2abf Bjorn - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
