Latest working kernel version: (Works with Redhat 4 kernel) Earliest failing kernel version: 2.6.24 Distribution: Self, kernel.org's kernel version 2.6.24 Hardware Environment: Dell 2950 Software Environment: Linux from Scratch, kernel version 2.6.24 Problem Description: I am using the latest kernel 2.6.24. The hardware unit is a 2950 Dell box. The firmware version of bnx2 is 2.9.1. The bnx2 driver does work with other flavors of Cisco Switches like 290x. It is having problems at a customer site who has a Cisco 650x. The customer tried the RHEL 4 and does seem to work fine. The RHEL4 comes with the version of bnx2: 1.4.38 The version on 2.6.24 is 1.6.9. Can anyone give me pointers as to why this is broken? Where can I get a patch? Any help is appreciated. Steps to reproduce: The driver does not auto-negotiate, neither does it work with a fixed link speed.

Can you provide some error messages and traces that you see? Has it been any change in driver behavior since the time of reporting?
Looks like the NIC is not linking up when connected to the Cisco switch. Please provide the output of: ethtool ethx mii-tool -vvv ethx with cable connected to Cisco switch.
