Hi, sorry for this non-proffesional way of sending bug report and patch (I'm new to Linux, couldn't find utility to create patch). Fix is based upon of the code analysis rather (and obviosly my working environment) then 3Com tech docs. Anyway lets start... 1. Bug Summary Inproper interface setting in 3Com 509 nic driver 1.16 (2.2) 2. Bug Description Bug exists in 3Com 509 nic driver version 1.16 (2.2) by Donald J. Becker. Under some circomstances the nic interface (10BaseT, AUI, BNC) is set inproperly usually causing the card to stop working. The unwanted and/or strange behaviour occures esspecially with more then one 509 nics present. Internally the code sets the interface type in if_port variable. It is set upon of eeprom value in several places depending on the nic type: PnP, ISA, EISA. After if_port assigment code flows to found: label in which the different parameters are gathered together (to dev variable) to set the nic. Unfortunatelly in that place if_port is used condidionally which I believe is inherited from previous driver versions. /* Fix is simple enough not to include any attachments. Here it is */ The line (around #451) dev->if_port = (dev->mem_start & 0x1f) ? dev->mem_start & 3: if_port; should be replaced simply with dev->if_port = if_port; 3. Keywords networking, kernel, 3Com, 3C509, modules, drivers 4. Kernel version I checked buggy driver is distributed with kernel version 2.2 and 2.4.2 (and probably all earlier kernel versions dated after Feb 1998).
