Description Pete Zaitcev 2010-05-08 22:14:15 UTC
Description of problem:

When loading e1000e, the interface is not detected and cannot be brought up.
The following is seen in dmesg:

e1000e: probe of 0000:00:19.0 failed with error -2

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

2.6.32-19.el6.x86_64

How reproducible:

Synchronous, but needs a given hardware

Steps to Reproduce:
1. Reboot
2. modprobe e1000e
  
Actual results:

Failure to detect and initialize the interface

Expected results:

Working like RHEL 5

Additional info:

Upstream never had it working right, I think. Something is special
about the e1000e driver in RHEL 5, but I don't know what. Hasn't
tried to diff them yet.

Comment 6 Andy Gospodarek 2010-05-18 15:19:05 UTC
Pete, I presume the patch attached in comment#5 fixes the issue for you?

Did a BIOS update fix it too or were you not able to try that?

For reference this is the upstream patch in comment #5:

    e1000e: Reset 82577/82578 PHY before first PHY register read

Comment 7 Pete Zaitcev 2010-05-18 23:27:38 UTC
Unfortunately, no, the patch in comment #5 does not work. It was suggested
that the firmware update may fix it on this box (Intel D3CB1). I'm trying
to find it. Our QA folks supposedly had an ISO somewhere (Intel Premier
seems sadly useless, therefore the delay).

Comment 8 Andy Gospodarek 2010-05-19 00:06:47 UTC
That's too bad.  I've been seeing errors with e1000e lately that appear to be 'fixed in firmware' but I've been holding out hope that there are some software workarounds too.  Looks like that is not the case with this one. :-/

Comment 9 RHEL Program Management 2010-07-15 14:09:56 UTC
This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release. It has
been denied for the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **

Comment 10 Andy Gospodarek 2010-07-15 14:16:11 UTC
Pete, can you test the latest kernel again?  I've added a bunch of e1000e patches since you opened this -- several of them resolved PHY issues.  Also did this only happen when PXE booting or all the time?

Comment 11 Pete Zaitcev 2010-07-15 16:34:00 UTC
I can test. Do you mean latest upstream or latest RHEL 6? If upstream,
from what tree (I would prefer Linus' -rcX tip).

BTW, the firmware upgrade fell through. Intel posted an update, but they
specifically excluded the mainboard type that I have as too old.

Comment 12 Andy Gospodarek 2010-07-15 18:05:03 UTC
Latest RHEL6, was all I was asking.  You can test the latest from Linus' tree if you like for a data-point if you like.

If this is an Intel SDV that they are no longer supporting we can try and make something work, but unfortunately their lack of support doesn't make me interested in working too much on it either.

I can find a way to ship you another card if you really need one. :-)

Comment 13 Pete Zaitcev 2010-07-23 15:11:40 UTC
Latest git of RHEL6 (2.6.32-50) isn't helping.
I think it's a lost cause, closing.
