If the patch has been in Wily, I don't think Wily should have this bug. Please test Wily to confirm this. -- 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/1292400 Title: task systemd-udevd

I checked with Matthew and found Matthew only applied the first patch [1]; after I applied the second patch [2], I'm no longer seeing any crash or memory corruption issue in Matthew's VM. BTW, the Windows Server 2019 host running Matthew's VM doesn't work with NIC SR-IOV correctly: when SR-IOV is

I installed and tested the 5.8.0-1034-azure kernel and it worked as expected. I created a Ubuntu 20.04 VM and installed the “5.8.0-1034” kernel this way: 1. Enable the “proposed” kernel by running the below as “root” (refer to https://wiki.ubuntu.com/Testing/EnableProposed): cat
