This problem still persists in kernel 5.19.3.
As mentioned before, f2fs_gc stays at 100% CPU utilization indefinitely:
247 root 20 0 0 0 0 R 99.7 0.0 90:30.67 f2fs_gc-8:4
Here is the call trace causing a hang:
kernel: INFO: task f2fs_ckpt-8:4:244 blocked for more than 122 seconds.
kernel: Not tainted 5.19.3-arch1-1 #1
kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this
message.
