Description Wade Mealing 2009-04-22 06:50:08 UTC

Description of problem:

e1000 card that comes up and works on boot in in 2.6.9-55, no longer works correctly in  2.6.9-78.0.13.ELsmp

Version-Release number of selected component (if applicable):

2.6.9-78.0.13.ELsmp

How reproducible:

Every time

Steps to Reproduce:
1. Have a working system running 2.6.9-55
2. Update to  2.6.9-78.0.13.ELsmp 
3. Reboot
  
Actual results:

The card will not function (accept/transmit) packets. An ifconfig down ifconfig up will solve the problem.


Expected results:

Card to work correctly.

Additional info:

The card using the e1000 (not e1000e) driver.

Setting Regression flag.  This may be a blocker -- this worked in an earlier release and no longer works.

2.6.9-55 was the kernel from RHEL 4.5.
2.6.9-78.0.13 is from RHEL 4.7.z

To narrow the problem down at least a little bit, could you please try the kernel from RHEL 4.6 (ie. 2.6.9-67)?

Meanwhile I'll see if there are any hints in the sosreport. Can we also have a sosreport from the working kernel version?

Not reproducible on hp-dl360g5-01.rhts.bos.redhat.com which contains the same PCI ID:

Comment 8 Michal Schmidt 2009-04-22 16:50:07 UTC

I uploaded six older versions of the e1000 driver to http://michich.fedorapeople.org/bz497046/

I suggest you download them all and try them one by one with the kernel you have.
For example for the first one:

# overwrite the e1000.ko module with the testing one
cp e1000-2.6.9-55.20.ELsmp.ko /lib/modules/2.6.9-78.0.13.ELsmp/kernel/drivers/net/e1000/e1000.ko
Then reboot and see if it works or not.
Repeat for the other ones.

This should help find which change caused the regression.
Thanks.

Hello,
do we have any of the results yet? Since this can be a blocker, it's quite urgent to have it fixed.

There have been several changes in e1000 in RHEL4.8, so it would be nice to test if it happens with 4.8 kernel too:
