Description

Found a machine running il-gate 20140821 entirely unresponsive local or remotely, console showed 1, which just contains the message

arl_dlpi_pending unsolicited ack for DL_UNITDATA_REQ on vnic999

repeated endlessly.

Didn't get a core yet, machine did not have apic_panic_on_nmi set and hadn't actually panicked, so...

I've fixed that, and if this recurs, we'll have more to go on. For now, just a data point for anyone else who stumbles upon this...it could be caused by more than one thing of course, but still.

No data to display
