Now I get the following:
$ dmesg | grep -i apst
[ 2.232133] nvme nvme0: apsta = 0, no APST
[ 2.448134] nvme 0000:04:00.0: NVME_QUIRK_NO_APST
[ 2.448135] nvme 0000:04:00.0: disabling APST.
[ 2.448137] nvme nvme0: apsta = 0, no APST
It seems like those messages are telling me that apst should be disabled?
However, I still get
sudo nvme get-feature -f 0x0c -H /dev/nvme0
get-feature:0xc (Autonomous Power State Transition), Current value:0x000001

Title:

I was affected by this bug
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1678184?comments=all
before. After disabling APST by adding
"nvme_core.default_ps_max_latency_us=0" in /etc/default/grub, the bug went away.
Since yesterday, however the bug has returned, with the system dying
with I/O errors after an hour or so.
I verified, that the kernel option is still being set
$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-4.10.0-22-generic.efi.signed
root=UUID=365f1a9c-9598-4ad5-a387-d02f771767a1 ro quiet splash
nvme_core.default_ps_max_latency_us=0 vt.handoff=7
however it turns out that it is being ignored for some reason, and
running
$ sudo nvme get-feature -f 0x0c -H /dev/nvme0
reports that APST is enabled. I can successfully disable it manually
using
$ sudo nvme set-feature -f 0x0c -v=0 /dev/nvme0
and the problem goes away. However, after any reboot and even after
waking the system from suspend, it is reenabled, causing the system to
crash after a short while.
