This bug is awaiting verification that the linux-starfive/6.2.0-1004.5 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-lunar-linux-starfive' to 'verification-done- lunar-linux-starfive'. If the problem still exists, change the tag 'verification-needed-lunar-linux-starfive' to 'verification-failed- lunar-linux-starfive'.
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.

Regression potential: Change adds additional calls to populate sysfs related to MSI devices. Any issues would be withing those limits. --- Original Description --- Let's say you launch a Xen-based EC2 instance with enhanced networking, then under kernel-5.19 you'll not see anything under $ ls /sys/class/net/ens3/device/msi_irqs/ This can be fixed by backporting https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=335b4223466dd75f9f3ea4918187afbadd22e5c8 (It got already backported to 6.1 and 6.3) With this patch applied, you'll correctly see the sysfs files: $ ls /sys/class/net/ens3/device/msi_irqs/ 690 691 692 693 694 695 696 697 698 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2022354/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
