Interwoven dmesg output?

[Mel Pilgrim]

The dmesg output shows this odd behaviour where the probe lines aren't 
properly serialized:

ada1 at ahcich3 bus 0 scbus3 target 0 lun 0
ada1: nvd1: <Samsung SSD 970 PRO 512GB> NVMe namespace
<ST8000NM0045-1RL112 MPC2> ACS-3 ATA SATA 3.x device
ada1: Serial Number ZA16F3S4
ada1: 600.000MB/s transfersnvd1: 488386MB (1000215216 512 byte sectors)
  (SATA 3.x, UDMA6, PIO 8192bytes)
ada1: Command Queueing enabled
ada1: 7630885MB (1953506646 4096 byte sectors)

I don't mind whole lines being out of order, but the nvd1 line showing 
up in the middle of the second ada1 line doesn't seem right.  What's 
happening here?
