tg3 driver v3.43-rh in kernel 2.6.9-34.EL fails to initialize first VLAN interface
Last modified: 2007-11-30 17:07:24 EST
Description of problem: I have a RHEL4 system (Dell 2650) that uses an 802.1q
VLAN trunk to connect to multiple subnets. This has worked fine for some time,
but upon upgrading to kernel 2.6.9-34.EL one of the VLAN interfaces stopped
working. The interface works fine if I boot back to 2.6.9-22.0.1.EL. After
some experimentation I found that whichever VLAN interface is brought up first
fails to work; the others are fine. The network port is Tigon3
[partno(BCM95703A30) rev 1002 PHY(5703)]. I believe the updated tg3 driver
(v3.43-rh) in this kernel is the culprit, because I have a Dell 2850 with e1000
interfaces in a very similar configuration and the VLAN interfaces work fine on
Version-Release number of selected component (if applicable): 2.6.9-34.EL (tg3
How reproducible: Always
Steps to Reproduce:
1. Define multiple VLAN interfaces on RHEL4 kernel 2.6.9-34.EL using a tg3
2. Boot the system
3. Observe that the first-initialized VLAN interface will not pass any traffic.
Actual results: VLAN interface passes not traffic and is not pingable.
Expected results: VLAN interface should work. :)
Additional info: Upon googling I found a similar bug reported for CentOS here:
this looks like a duplicate of 188087 which we have fixed in the U4 beta...if
you want to try that kernel: http://people.redhat.com/~jbaron/rhel4/
Please re-open this if this is a separate issue.
