Seems like similar bug as....
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1521173
Steps To ReproduceRun airodump-ng to the wan/usb interface.
Log fills rapidly to TB's and system then effectively halts due to drive being full!!
Additional InformationWorkaround - Disabled aer and msi in the kernel boot options for grub.

**When AER is enabled, a PCI Express device will automatically send an error message to the PCIe root port above it when the device captures an error. The Root Port, upon receiving an error reporting message, internally processes and logs the error message in its PCI Express capability structure

/etc/default/grub

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`

The driver does not appear to have aer support, who owns this ?.
