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.

[Fix] Rescan the bus in order to reprobe the device to avoid mac80211 layer gets messed up. [Test] With the fix in place, system keeps working after firmware issue occurs. Verified with thousand times of suspend. [Where problems could occur] If the firmware/hardware is really dead and beyond recoverable, the same process can be triggered again and again. == Original bug report == During the jammy-hwe migration test, I found some machines failed to run the pm-graph. test(https://github.com/canonical/checkbox/blob/main/providers/base/units/stress/jobs.pxu#L604) One of machine when I rerun it locally, it passed, but others are still failed.
