[OpenIndiana-discuss] received unsolicited ack for DL_UNITDATA_REQ on bnx0arl_dlpi_pending

[Schweiss, Chip]

Were you able to resolve the cause of this?

I found this thread today when one of my servers started having the same
problem.   Hard lockups with the nearly the same message on the console.

My affected server is a Supermicro 6037R-TXRF with the X9DRX+-F
motherboard.   It has 2 Intel nics.  The console message reads:

received unsolicited ack for DL_UNITDATA_REQ on igp0arl_dlpi_pending

It repeats 4 times and the system locks.

This system is completely unloaded and the problem occurs after only a few
minutes of uptime.

Thanks for any additional info you can provide.
