[Bug 2053251] Re: performance: Scheduler: ratelimit updating of load_avg

This bug is awaiting verification that the linux-xilinx-
zynqmp/5.15.0-1029.33 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-xilinx-zynqmp'
to 'verification-done-jammy-linux-xilinx-zynqmp'. If the problem still
exists, change the tag 'verification-needed-jammy-linux-xilinx-zynqmp'
to 'verification-failed-jammy-linux-xilinx-zynqmp'.


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. Thank you!
