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 1847340

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'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Test results with stress-ng.

The original kernels hit the issue (very often on Bionic, less often on Focal.)
The modified kernels don't (in 2x the number of runs on both Bionic and Focal.)

Number of tests (stress-ng + crash + mount) that mount PASSED or FAILED (ie, problem was hit.)

This bug is awaiting verification that the linux/5.4.0-89.100 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-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

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.
