Hi,

It seems that this issue is due to DMA. But... i can't find where is
the setup of dma for pci bus for bcm6358

[LEDE-DEV] issue with rt61-pci

2016-09-25 Thread Eddi De Pieri 
Hi,

I've just flashed an old device with onboard a rt2661 pci card.


Lede-Trunk/Openwrt 15 and trunk:
by using the wifi card(AP mode) dmesg show:
[  257.472000] ieee80211 phy1: rt61pci_txdone: Warning - TX status
report missed for entry 28
[  257.48] ieee80211 phy1: rt61pci_txdone: Warning - TX status
report missed for entry 29
[  257.488000] ieee80211 phy1: rt61pci_txdone: Warning - TX status
report missed for entry 30
[  257.496000] ieee80211 phy1: rt61pci_txdone: Warning - TX status
report missed for entry 31
[  257.504000] ieee80211 phy1: rt61pci_txdone: Warning - TX status
report missed for entry 1
(don't remember which distribution i used to get this log... but all
suffer of the same issue)

and after few seconds of usage the wifi card stop working and it need
a reboot or rmmod rt61-pci/modprobe to make it work again for few
seconds

it seems that other people even on desktop systems get same error and
is not clear if it is solved on latest ubuntu as well there is already
a ticket opened on openwrt: https://dev.openwrt.org/ticket/18228

On Openwrt 12.09 work correctly.

Have you any idea about what could have introduced this regression?
I've seen that between 3.3.8 and later kernel we use DTS, perhaps is
missing some definitions for pirelli a226m device or something else
more cfg80211 related?
