This bug is awaiting verification that the linux- gcp-5.4/5.4.0-1140.149~18.04.1 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-bionic-linux- gcp-5.4' to 'verification-done-bionic-linux-gcp-5.4'. If the problem still exists, change the tag 'verification-needed-bionic-linux-gcp-5.4' to 'verification-failed-bionic-linux-gcp-5.4'.
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.
