Comment (by bittorf@…):
i have the same issue on TP-LINK TL-WR1043ND with r42884.
i use adhoc+ap on one radio - adhoc is working fine in this situation,
only 1 message in klog:
{{{
[39466.900000] ath: phy0: Failed to stop TX DMA, queues=0x004!
}}}
the router can hear other stations/laptops end responds for DHCP-requests
but the laptops dont receive them. restarting dnsmasq does not help, but
doing a 'wifi' - everything works normal again.
