Problem in 4.8.0-22, looks to have been fixed

[Ian]

It looks to have been fixed in 4.8.026, but the previous version of the kernel was complaining bitterly, possibly when an SD card reader was unplugged.

The first time it happened, two days ago, it was noticed when the partition with /var/log ran out of space thanks to the volume of messages to kern.log and syslog.

The second time, yesterday, it was spotted before then:

I can plug in and remove the reader without this happening following today's update.

The four requested files are attached, but this is with the new version where it's not happening.
