Overall good.
This got fixed for me: Suspend lockup on Gigabyte MB Intel Rocket Lake since 5.15
Sole issue so far is a btrfs HDD drive acting up. The drive is used for backups mirroring the main drive: backup the snapshops twice a day for a few minutes and sleep the rest of the time. In 5.16 the btrfs-cleaner process never settles and is spiking constantly. Other btrfs drives are fine, it’s just this one.
