dmesg output on BPi Pro with PMP

[jimbolaya]

I've got a BPi Pro with a PMP as a sort of backup box. 

 

It appears to be running find so far and I'm not running RAID of any sort on it as I've had issues with that an PMPs on other platforms. 

 

The question I have is dmesg is filling up with entries like this:

 

[66451.217935]  sdb: sdb1
[66752.272509]  sdb: sdb1
[66752.593223]  sdd: sdd1
[67964.907826]  sdc: sdc1
[67974.038562]  sdd: sdd1
[68595.107245]  sdb: sdb1
[69525.179964]  sdb: sdb1
[69835.958729]  sdd: sdd1
[70766.572499]  sdb: sdb1
[71076.828494]  sdb: sdb1
[71377.605195]  sdd: sdd1
[72298.301984]  sdb: sdb1
[73219.937015]  sdd: sdd1
[73637.287585]  sdb: sdb1
[73637.660971]  sdd: sdd1
[73840.037079]  sdb: sdb1
 

For any particular disk, they appear to go away once the partition is mounted, but I'm curious to know what the information is being attempted to be communicated and whether I should be concerned.

 

I'm currently running ARMBIAN Debian GNU/Linux 8 (jessie) 4.9.12-sunxi.
