rge is a 2.5gb/s network adapter:
...
 rge0 at pci7 dev 0 function 0: Realtek Semiconductor 8125
10/100/1G/2.5G Ethernet (rev. 0x00)
rge0: interrupting at msix5 vec 0
rge0: Ethernet address 00:8e:25:79:05:3c

which should not have been busy at the time; the system was close to
completing a full build of aarch64 -current.
