[Bug 1425699] Re: kernel panic on IBM Power8 PPC MAAS ephemeral image
I will not change the status of this bug because I can not reliably rule out that the initial issue still exists. That was reported to happen not all the times and from the stack trace involved some locking issue in the pci scsi adapter's driver. Since comment #9, however, the reported stack trace is showing a completely different issue. This happened to be a regression since 3.13.0-46 and in order to cleanly separate the problems I opened LP: #1589910 to track the fix for that. As soon as that is there should be no need to enforce a HWE kernel for commissioning and/or provisioning of ppc64el hosts. Should the initially reported problem persist then, please report back here so we can try to fix that, too. Note that the stack trace should involve the IPR adapter in some way.

[Bug 1425699] Re: kernel panic on IBM Power8 PPC MAAS ephemeral image
We ran into this while setting up an OpenStack cloud using IBM POWER8 machines[1]. Unfortunately, hwe-v for Trusty isn't available (LP:1504066) but hwe-u does indeed fix the "Oops: Exception in kernel mode, sig: 4 [#47]" boot loop we ran into. Since it's been advised here, and in several other bugs that POWER8/ppc64el doesn't work with the main Trusty 3.13 kernel, perhaps we could make MAAS images default to hwe-u and above for ppc64el?

[Bug 1425699] Re: kernel panic on IBM Power8 PPC MAAS ephemeral image
Per Mike's testing, this is now resolved by pushing more recent images to Releases that enable hwe-u in Trusty for PPC64EL. So from the initial bug point of view, this is fixed and could be marked as such. However, as this also affects everything that's NOT ppc64el, I'd suggest leaving it open until such time as the images have been tested and pushed for the other archs as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1425699 Title: kernel panic on IBM Power8 PPC MAAS ephemeral image To manage notifications about this bug go to: https://bugs.launchpad.net/maas-images/+bug/1425699/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Next, I deleted all the images I had and switched over to the Daily stream. First, I downloaded ONLY 14.04 amd64. Once that was ready, I ensured the Arch was set to amd64/hwe-u and again attempted commissioning. So using the 14.04 images only from Daily, I was able to successfully commission using the hwe-u kernel according to the boot messages that said it was booting ephemeral-ubuntu-amd64-hwe-u-trusty-daily To verify this, I then deployed with the node set to amd64/hwe-u, Default OS, Default Release (14.04LTS). After deployment I confirmed that it was running what appears to be 14.04.2 with a 3.16 kernel (3.16.0-37). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1425699 Title: kernel panic on IBM Power8 PPC MAAS ephemeral image To manage notifications about this bug go to: https://bugs.launchpad.net/maas-images/+bug/1425699/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Jeff, If you mark a system in maas as 'generic/hwe-u', then you will boot installation with the hwe-u kernel, the install will install the hwe-u kernel, and everything is happy. generally speaking my experience with power is you need hwe-u. hwe-t kernels are not stable on ppc64el. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1425699 Title: kernel panic on IBM Power8 PPC MAAS ephemeral image To manage notifications about this bug go to: https://bugs.launchpad.net/maas-images/+bug/1425699/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1425699] Re: kernel panic on IBM Power8 PPC MAAS ephemeral image
Added this to maas-images. From chats with Mike, I believe that the Vivid ephemerals are stable on Power8. I suspect that what's happening (I have not looked too deeply into this so this is just a guess for now) that the ephemerals are built at GA time, and after that point only the filesystem tarball is built for the point releases/daily images. So even at 14.04.2, you're installing 14.04.2 filesystem but using a 14.04.0 ephemeral to do so. Unfortunately, We can not use vivid ephemerals to certify Trusty, so we need a full stack of Trusty images for the power machines. This bug is currently gating PowerNV certification so I consider it a critical bug. ** Also affects: maas-images Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1425699 Title: kernel panic on IBM Power8 PPC MAAS ephemeral image To manage notifications about this bug go to: https://bugs.launchpad.net/maas-images/+bug/1425699/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1425699] Re: kernel panic on IBM Power8 PPC MAAS ephemeral image
Looking at the commission.log, it appears that the h/w is reporting something is broken and that is not handled properly. Do you happen to know if this happens on more than one machine? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1425699 Title: kernel panic on IBM Power8 PPC MAAS ephemeral image To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1425699/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1425699] Re: kernel panic on IBM Power8 PPC MAAS ephemeral image
One additional note. The kernel version in the image is pretty out of date. The current version in -updates is 3.13.0-46.77. We may want to ask whoever maintains the images to create an image with a newer kernel for Trusty. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1425699 Title: kernel panic on IBM Power8 PPC MAAS ephemeral image To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1425699/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Was there a prior Trusty kernel that did not have the panic? Also, does this also happen with newer release, such as Utopic or Vivid? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1425699 Title: kernel panic on IBM Power8 PPC MAAS ephemeral image To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1425699/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
