This bug is awaiting verification that the linux-ibm-gt- fips/5.15.0-1052.55+fips1 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-linux-ibm-gt-fips' to 'verification-done-jammy-linux-ibm-gt-fips'. If the problem still exists, change the tag 'verification-needed-jammy-linux-ibm-gt-fips' to 'verification-failed-jammy-linux-ibm-gt-fips'.
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.
