Hi, > ============================== > > serial_pci_guess_board+0x49/0x170 SS:ESP 0068:c7c11ea4 > The problem seems to be in "serial_pci_guess_board" function in drivers/serial/8250_pci.c. Why don't you insert prink(s) here to find out the offending line of code? Also, are you using a PCI serial port? Try using the on board serial port?
