Hi Bjorn, your patch: commit 7e92b4fc345f5b6f57585fbe5ffdb0f24d7c9b26 Author: Bjorn Helgaas <bjorn.helgaas@xxxxxx> Date: Tue May 8 00:36:07 2007 -0700 x86, serial: convert legacy COM ports to platform devices disables probing using legacy code in favour of ACPI/PNP to avoid double discovery. However if SERIAL_8250_PNP is not enabled the user is left without serial ports (been there, done that - my kernel config suddenly wasn't working anymore). So: Enable probing of serial ports using legacy code when PNP code (SERIAL_8250_PNP) is not enabled.
