Thanks for your answer. In the meantime we have 3.2.0 arrived in Debian wheezy, so I tried again, and got exactly the same problem. I realized as well that they are handled by the "pch_uart" driver, I can modprobe, the driver "see" the devices and creates the associated /dev/ttyPCHn, but it just does not work :( Did you have any "real" success? (I mean physically connecting the 2nd serial?) I then traced the changes in the sources and decided to comment out the pci ids definitions in 8250_pci.c so that they aren't handled by "pch_uart" as they were not in the past... ... and now they are recognized again as ttySn, and it works perfectly :) Still need to figure out how to get the same result without recompiling a kernel, as I would prefer to stay on Debian stock kernel... -- Philippe _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
