Comment 5 for bug 1846237

Adding the kernel track to this bug after checking with Michael (IBM). Although the bug was found in a flavor kernel of Ubuntu, it sounds like (from the notes in the description) that this might a generic issue with 18.04.3 and newer kernels.

The next steps for IBM is to reproduce this issue on 18.04.3 or newer released kernel. Also, compare with the upstream kernel to see if issue was already fixed. You could use the mainline builds to compare https://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/
