BBB/I2C: Using ioctl(I2CRDWR) warns: interrupt storm detected on "intr70:"

[Winston Smith]

Continuing on with working with the I2C interface on the BBB I wrote a
utility to read the BBB's 28 byte system EEPROM on iic0, address 0x50
which contains the model and serial numbers.  See pastebin here:

However, when I run the utility:

root at beaglebone:~ # ./bbb_eeprom
Read from slave 50 on /dev/iic0, signature=AA:55:33:EE
Model:  A335BNLT0A6A
Serial: 0214BBBK4321


I see the following warning on the console:

interrupt storm detected on "intr70:"; throttling interrupt source


Does this mean anything, or is it just a spurious warning.

BTW: This is with FreeBSD 11-CURRENT r265163.
