Re: problem with "serial" driver in kernel 3.16.0

Thankyou very much for your quick answers. I searched now in the linux sources for the problem and I think I could find it in the file linux-source-3.16/drivers/tty/serial/8250/8250_pci.c There is a function serial_pci_guessboard and a blacklist including the vendor- and device-ids of 3

[PATCH] nvmem: core: Handle shift bits in-place if cell->nbits is non-zero

[PATCH 3/7] phy: add proper phy struct device refcounting

Take a refcount on the phy struct device when the phy device is attached to a network device, and drop it after it's detached. This ensures that a refcount is held on the phy device while the device is being used by a network device, thereby preventing the phy_device from being unexpectedly

[PATCH 7/7] phy: add phy_device_remove()

Add a phy_device_remove() function to complement phy_device_register(), which undoes the effects of phy_device_register() by removing the phy device from visibility, but not freeing it. This allows these details to be moved out of the mdio bus code into the phy code where this action belongs.
