I am not in favor of an automatic rebuilding of initrd as it can cause some customized configuration lose or other undesired results, like if one of the drivers has load issues it can cause system crash upon boot.

Of course, you are welcome to update the release notes.

PS: As you know, it will not help the one ignoring reading the release notes :)

Thanks for the quick response.

Perhaps it should be documented in a more generic  way, as this is not only 
related to openibd
But to all drivers part of the initrd.

And for next versions, maybe it should be part of the build script ? with dracut -f 
--add-drivers <driver> for every driver in compat-rdma?

Hi Michal,

This issue is documented already in the OFED_release_notes.txt:

3. Known Issues

22. Bug 2640 - openibd fail to start when system is coming up:
      The inbox kernel modules being loaded from initrd
      So, need to rebuild the initrd by:
      # dracut -f -v

Hi Vlad and All,

During soft-forge testing of the package containing the fixes, we hit
a different issue which I believe could affect all vendors

The problem is when drivers are part of the initramfs/initrd of the distro as
they come inbox.
In our case qed/qede are inbox, but qedr is not. Meaning that qed/qede
are in initrd and loaded automatically with older version than the one
installed by OFED. Then when qedr is probed there is a mismatch, as the
OFED qedr version is newer and incompatible.
If the qedr was inbox as well, we probably wouldn't have even noticed that
OFED drivers aren't loaded.
(they will be loaded only after an rmmod of all qed drivers and
modprobe )

In our Out-of-box installation scripts, we update the initramfs with
the newly compiled drivers. I'd expect to see the same at the end of
an OFED build ( dracut -f / update initrd, mkinitrd etc... for example

We could just document this for the user to rebuild the ramfs after OFED
I'm not sure how this didn't come up until now, I've looked a bit on
our setups and noticed that a lot have omit-drivers in the lsinitrd or older
drivers that We're installed etc... this is easy to miss. In addition, the only
reason we did hit this is because the inbox / ofed drivers are mismatched...

Hello Michal,

Great progress, kudos to the team for a quick resolution. I concur,
let's test before we roll RC3.

Vlad, please pull these fixes into new daily build so Brendan can test.


Hi Arlin,

We've been working with Brendan on this and were able to reproduce
on our setups fix, and test locally.
There are three commits (2 fix the issue and 1 fix was exposed that
our data collection had an issue)
2 out of the 3 fixes have already been upstream in official linux revisions.
one of the fixes can't go through next as is as the code varies quite a bit.

Brendan will only be able to fully verify the fix Monday / Tuesday.

The commits that need to be pulled are in my github:


I would prefer Brendan gave this a test before rc-3. But I
understand we're on a tight timeframe.

Quick update on RC3..

Broadcom has all critical bugs fixed and included in a new daily build.

Our final blocking item is a critical "perftest hang" issue on a
QL45412 RoCE adapter.

Bug 2674<http://bugs.openfabrics.org/bugzilla/show_bug.cgi?id=2674>
"Unable to complete RDMA applications (perftest)".

Michal, can we please get an ETA for the fix or a "won't fix"
disposition so we can push forward with RC3?
