Description

We're using madwifi-ng 0.9.4 on MIPS and experience occasional kernel panics resulting in a reboot.

In dump1: ath_tx_processq+0x2f4 objdump is at address 83f4:

/var/tmp/portage/madwifi-ng-0.9.4/work/madwifi-0.9.4/ath/if_ath.c:7344
    83f0:       8e030004        lw      v1,4(s0)
    83f4:       8c620abc        lw      v0,2748(v1)
    83f8:       24420001        addiu   v0,v0,1
    83fc:       ac620abc        sw      v0,2748(v1)
if_ath.c:7334 looks like:
       ni->ni_ic->ic_wme.wme_hipri_traffic++;

In dump2 it crashes in ieee80211_node.c, which is called from

  ath.c:7385 ieee80211_free_node(ni); 

Both cases suggest that 'ni' is somehow corrupt.
