Hmm, that looks like it should work.  I wonder why it didn’t seem to go well for me.  I’ll give it another shot.

Manoj, how do you recommend utilizing the PPA?

I downloaded the debian packages for linux-image and headers, used dpkg to install, and while it boots, many of the drivers are missing, so the test case cannot be executed.

The instructions to add the ppa and install the kernel etc are in the PPA:
https://launchpad.net/~centriq-team/+archive/ubuntu/test/

in brief:
sudo add-apt-repository ppa:centriq-team/test
sudo apt-get update
sudo apt-get install linux-image-4.10.0-20-generic linux-image-extra-4.10.0-20-generic

If you have multiple versions of the kernel installed on your system and if you want to stop at the grub menu to select your kernel... you need to edit /etc/default/grub and comment out "GRUB_HIDDEN_TIMEOUT=0"  before you install the kernel package (if you edited after you installed you can just run sudo update-grub2). This will drop you into the grub menu, where you can go into the "Advanced" tab and select the kernel you want to boot.


I attempted to go through DI, but pointing DI to the test PPA does not seem to install the correct kernel, and leaves the system in a non-bootable state.

Joseph,

Thanks for testing. Have you tested the kernel in the centriq test PPA with the patch applied? Or was it an upstream kernel? If you tested the kernel in centriq test PPA could you please post your test results here?

Thanks
Manoj

Hi,

I already test the patch on REP and it really fix the kernel panic issue.

Jeff,

Could you please test the kernel in PPA https://launchpad.net/~centriq-team/+archive/ubuntu/test/ <%20https:/launchpad.net/~centriq-team/+archive/ubuntu/test/%20> that has Joeseph Chang's patch ipmi: Fix kernel panic at ipmi_ssif_thread() on a QDF2400 REP system and report your results? http://bugs.launchpad.net/bugs/1689886 <%20http:/bugs.launchpad.net/bugs/1689886%20>

When you report the test results please include the output of the working ipmi command.

Thanks
Manoj Iyer
