There's a tentative fix being tested upstream. While I can reproduce
the problem, it's a pretty narrow workload (e.g. untar firefox
source). Launch, boot, updates, seem normal or faster compared to 5.9.
The effect is worse on SSD than HDD, making an SSD about as slow as a
HDD for the affected workload.
