Comment 105 for bug 1678184

Hi Kai-Heng, thanks!

Overnight I've used `nvme_core.default_ps_max_latency_us=0` in GRUB with no read-only crashes (everything has been smooth). I left the machine awake all night, I've since suspended & awoken it twice, all seems to be ok.

As expected all APSTE is disabled:
`
$ sudo nvme get-feature -f 0x0c -H /dev/nvme0
get-feature:0xc (Autonomous Power State Transition), Current value:00000000
 Autonomous Power State Transition Enable (APSTE): Disabled
