Or simply enable the workaround even for sane hardware like it is done here: https://dev.openwrt.org/browser/trunk/target/linux/ar7/patches-2.6.30/500-serial_kludge.patch as this patch has no side effect on working hardware. > > Annoyingly I'm guess we are more interested in people who do *not* have > the bug and we would not hear from them as a result.
