Bug Description
This new laptop has a Samsung NVME SSD. The SSD (or the SSD controller) sometimes fails to resume from standby. The probability of this goes up with the time the laptop is on standby & I have to save all files when I put the laptop on standby at the end of the day as most likely it won't resume successfully.
When I try & resume, normally the laptop appears to resume, I can unlock the screen but there's no disk access. Any programs that were in memory when I suspended the laptop are OK but everything else fails with an I/O error.
The syslog includes entries like the following.
nvme nvme0: Device not ready: aborting reset
nvme nvme0: Removing after probe failure status: -19
Sometimes the first of these is repeated.
Here is the relevant line from lspci.
