APAR status
Closed as program error.
Error description
Sometimes when using dlpi, a receive interrupt and processing of the receive queues can nest deep enough to overrun the space allocated for the interrupt stack. The stack will be very long but is sometimes obscured because a panic is hit in call_v_adspace_switch. The stack will have several calls to dlpirsrv, sq_wrapper, csq_run, csq_turnover, and csq_lateral.
Local fix
Problem summary
Customer would experience a system crash.
Problem conclusion
Appropriate code changes made to include a new option in the /etc/dlpi.conf to make dlpi run to spec. After this APAR is applied, by default we will run NOTTOSPEC. A sample line would be: d+ dlpi tr,s,r /dev/dlpi/tr
