This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- artful' to 'verification-done-artful'. If the problem still exists, change the tag 'verification-needed-artful' to 'verification-failed- artful'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

This is triggered by issuing a bus or a slot reset on the PCI device. [Fix] The following patches checks indicate that the reset is not possible preventing the kernel panic. 357027786f35 PCI: Avoid bus reset if bridge itself is broken 822155100e58 PCI: Mark Cavium CN8xxx to avoid bus reset 33ba90aa4d44 PCI: Avoid slot reset if bridge itself is broken These patches are already in Bionic, we need these patches in Artful so that xenial linux-hwe also has the fix. The platforms of interest were certified with Xenial and linux-hwe, so we are interested in fixing this only in Artful. [Test] - Artful Host with Artful/bionic guests - Pass though PCI device (vfio-pci) from Artful to bionic and make sure its usable. - The device should pass through and not cause a kernel panic. + A test kernel is available in ppa:manjo/lp1770254 + [Regression Potential] None. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1770254 Title: [SRU][Artful] using vfio-pci on a combination of cn8xxx and some PCI devices results in a kernel panic.
