This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 2011389

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

The lack of proper lock begins since commit 185a383ada2e ("x86/PCI: Add driver for Intel Volume Management Device (VMD)"), v4.4, but we only bump into this issue in 6.1 oem/generic kernels or above.

SRU:
* http://ckctreview.internal/r/c/linux-oem/jammy/+/1860 (linux-oem-6.1/jammy)

SRU: https://lists.ubuntu.com/archives/kernel-team/2023-March/137761.html (lunar, unstable)

While we cannot reproduce this on kernels older than 6.1, we will skip this.

This bug is awaiting verification that the linux-oem-6.1/6.1.0-1009.9 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-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

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.
