Thanks for testing!
I cannot do much based on the information provided.
Could you recompile with IWM_DEBUG defined, and perhaps place a few
additional printfs at strategic locations, to figure out which
firmware command is last sent before the firmware crashes?
That would help me a great deal.
If you don't want the firmware to be restarted over and over so it
won't print these lines repeatedly, disabling the init_task which
attempts to recover from firmware crashes might help:
if (r1 & (IWN_INT_SW_ERR | IWN_INT_HW_ERR)) {
printf("%s: fatal firmware error\n", sc->sc_dev.dv_xname);
/* Dump firmware error log and stop. */
iwn_fatal_intr(sc);
iwn_stop(ifp, 1);
task_add(systq, &sc->init_task); <-- remove this line
return 1;
}
