RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Flavio Leitner 2011-01-20 17:26:28 UTC 
Description of problem:
The Marvell Yukon 88E8059 PCI-E Gigabit Ethernet is unsupported and so doesn't work.

Version-Release number of selected component (if applicable):
2.6.32-85.el6

Actual results:
NIC is undetected, doesn't work.

Additional info:
There is an upstream commit[4] adding support to this NIC. However, the RHEL-6 kernel needs few more commits to address the patch dependencies.

Depends on, in order:
[1] e91cd2e65f22a80af87367178bed4957fdc45ecd
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=e91cd2e65f22a80af87367178bed4957fdc45ecd

and finally the patch adding support to the customer's NIC:

[4] 0f5aac7070a01ec757ed243febe4fff7c944c4d2
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=0f5aac7070a01ec757ed243febe4fff7c944c4d2


I've backported each patch to -85.el6, grouped them in a single one and built a test package available at:
https://brewweb.devel.redhat.com/taskinfo?taskID=2963111

Customer reported this backtrace while testing it:

which seems to be the same as in upstream bugzilla below:
https://bugzilla.kernel.org/show_bug.cgi?id=20092

Thus, I've asked to test again with TCP timestamp disabled (sysctl -w net.ipv4.tcp_timestamps=0). It has worked out according with customer's feedback.
