Re: [Kernel-packages] [Bug 1641593] Re: unable to enable iommu on HPE Proliant Gen9 server
Doing some more testing it looks like the systems without the firmware udpate are not stable. I can sometimes, but not always, get them to boot using either 4.4.0-59-generic #80 or 4.4.0-62-generic #83, but once they're up, they don't last long. The longest I've seen is about 40 minutes before getting "sd 0:0:2:0: rejecting I/O to offline device" errors and /dev/sda going offline. I can get it to go offline quicker - almost immediately - by doing "cat /dev/urandom > /dev/sdb". The two systems with the firmware updates both reliably boot up and stay up using either 4.4.0-59-generic #80 or 4.4.0-62-generic #83, and haven't gone offline yet from the "cat /dev/urandom > /dev/sdb" test. I will leave them running over night.

Re: [Kernel-packages] [Bug 1641593] Re: unable to enable iommu on HPE Proliant Gen9 server
So, I appear to have spoken too soon on exactly what fixes this. We have two systems being tested with 4.4.0-62-generic #83 - one with the firmware update and one without. The one with the firmware updates has been up for over 6 hours now without any issues. The one without firmware updates has been up for 40 minutes and is getting I/O errors now. I'm also seeing a system with 4.4.0-59-generic #80 and no firmware updates boot up with iommu enabled, I will see how long it stays up.. I'll also test with 4.4.0-59-generic #80 and the firmware updates.

[Kernel-packages] [Bug 1641593] Re: unable to enable iommu on HPE Proliant Gen9 server
** Description changed: I'm using MAAS to enable the following kernel flags on install/boot: - iommu=pt intel_iommu=on + iommu=pt intel_iommu=on in order to be able to passthrough SR-IOV VF functions to KVM guess; however when these options are enabled, the servers fail to install (see attached screenshot). The install eventually fails - it looks like the writes back to one of the disks starts to fail for some reason. + + Servers are targeted with Xenial and the release 4.4 kernel (no HWE). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1641593 Title: unable to enable iommu on HPE Proliant Gen9 server Status in linux package in Ubuntu: Incomplete Bug description: I'm using MAAS to enable the following kernel flags on install/boot: iommu=pt intel_iommu=on in order to be able to passthrough SR-IOV VF functions to KVM guess; however when these options are enabled, the servers fail to install (see attached screenshot).
