Bug Description
This is a fresh posted connected to a very similar now-solved bug ("APST quirk needed for Samsung 512GB NVMe drive"): https:/
My NVMe is the less-common 1TB version. It exhibits similar (possibly identical) behaviour but has not yet been quirked.
I've followed up as Comment #101 but maybe I need to open this as a new issue? https:/
Specifically - using Kernel 4.19.0 on Mint 19.0 the default APST settings caused read-only errors within minutes-1 hour, this is fatal. Disabling APST solves the problem, I have this disabled in GRUB now. Reducing the APST settings but not disabling them does not stop the problem.
An example of the read-only result (copied from #101) that occurs if APST is left in its default state:
Oct 31 11:33:04 ian-XPS-15-9550 kernel: EXT4-fs (dm-1): mounted filesystem with ordered data mode. Opts: (null)
Oct 31 11:33:04 ian-XPS-15-9550 kernel: EXT4-fs (dm-1): re-mounted. Opts: errors=remount-ro
Oct 31 11:33:05 ian-XPS-15-9550 kernel: EXT4-fs (nvme0n1p1): mounted filesystem with ordered data mode. Opts: (null)
Oct 31 15:09:44 ian-XPS-15-9550 kernel: EXT4-fs (dm-1): mounted filesystem with ordered data mode. Opts: (null)
Oct 31 15:09:44 ian-XPS-15-9550 kernel: EXT4-fs (dm-1): re-mounted. Opts: errors=remount-ro
Oct 31 15:09:44 ian-XPS-15-9550 kernel: EXT4-fs (nvme0n1p1): mounted filesystem with ordered data mode. Opts: (null)
I had tried `nvme_core.
I've been using my laptop successfully (no read-only errors) for over a week having disabled APST including many suspend/awaken cycles. Prior to this every boot would crash and burn with read-only errors within an hour or so.
This is the drive and kernel (copied from #101):
$ sudo nvme list

I am of course happy to upload more info - let me know what's needed?
Could this be added as a quirk to the kernel please?
