[smartmontools-support] Reading NVME log

[Thane K. Sherrington]

The following report is from a Kingston SSD.  I've been having problems 
with booting with this drive - randomly I get messages that there is no 
boot device.  I'm not sure if it's the motherboard or the SSD.

The report says this:
SMART overall-health self-assessment test result: PASSED
Available Spare:                    100%
Available Spare Threshold:          100%

So that all looks good, but there are a lot of errors in the log, and 
I'm wondering if they are a bad sign.

Thanks!
