Since starting to use the "Intel Corporation Ethernet Controller 10-Gigabit X540-AT2 [8086:1528]" card on the MilkV Pioneer, this error has started occurring sometime after boot without fail.

[ 4066.488654] Disabling IRQ #63
IRQ 63 is the port I'm not using, but it is still generating interrupts until one isn't handled, then it is disabled. The active port is on IRQ 62 and continues to work, but I have also observed strange disconnects and connection corruption that may be related.
