This bug is awaiting verification that the linux- starfive-6.2/6.2.0-1008.9~22.04.1 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-jammy-linux- starfive-6.2' to 'verification-done-jammy-linux-starfive-6.2'. If the problem still exists, change the tag 'verification-needed-jammy-linux- starfive-6.2' to 'verification-failed-jammy-linux-starfive-6.2'.
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.

That causes higher overall power consumption. [Fix] Allow ASPM to be enabled. While at this, remove old cruft that can interfere upstream VMD driver. [Test] Check the value of `/sys/kernel/debug/pmc_core/slp_s0_residency_usec`. Now system can reach deepest power saving state during sleep. [Where problems could occur] Some NVMe may have I/O issue when ASPM is enabled. But for this scenario the issue will also appear when VMD is disabled.
