dracut won't picking up new mpt3sas driver after upgrading kernel to 4.4.2-301
Last modified: 2016-12-20 14:08:18 EST
Description of problem:
With kernel update 4.4.2-301.fc23.x86_64 driver mpt2sas have been replaced by mpt3sas so dracut won't picking up new driver and boot will fail.
Version-Release number of selected component (if applicable):
upgrade kernel to 4.4.2-301.fc23.x86_64
Steps to Reproduce:
1. dnf update -y kernel\*
3. fail to boot
failed boot/dracut fall into emergency shell
to fix this unexpected behaviour after kernel upgrade and *BEFORE* reboot need to be done:
# add new mpt3sas driver to initramfs image
dracut --force --add-drivers mpt3sas --kver=4.4.2-301.fc23.x86_64
# ensure that mpt3sas driver exist in initramfs image
lsinitrd -k 4.4.2-301.fc23.x86_64 | grep mpt3sas
# reboot machine

This seems like something that dracut needs to fix, not the kernel. The kernel has a modalias in mpt3sas for mpt2sas already:
[jwboyer@vader ~]$ modinfo mpt3sas

Also, what is the lspci -nnvv output for your MPT card? We can check that the mpt3sas driver has an alias for the PCI data as well.

*** Bug 1312178 has been marked as a duplicate of this bug. ***
Yes, manually including mpt3sas module solved the problem on DELL T7610. I did
get a screen message:
mpt2sas_cm0: Overriding NVDATA EEDPTagMode setting.
Whatever that means. Thanks.
I note, though it might be obvious: Once you've actually managed to get the newer kernel to boot, dracut will do the right thing and install the mpt3sas module without being told. So as long as you don't boot back to 4.3.x and then install a new kernel package, things should be OK.
Just to confirm the bug on a Dell Precision T7610 desktop with Fedora 22 in a normal update from kernel 4.3.6-201 to 4.4.3-201. Solved adding
to /etc/dracut.conf and generating a new initramfs for 4.4.3.
Yes, it was Fedora 23 on Dell Precision T7610. Subsequent kernels do fine
and don't need the add_drivers any more as explained in Comment 6.
Same issue going from 4.2.3-300 to 4.4.6-300 on a Dell Poweredge R815.
dracut --force --add-drivers mpt3sas --kver=4.4.6-300.fc23.x86_64
Fixed it for me.
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 23 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
