Hi,

I have wifi working on cubietruck, but after several minutes of operation 
it stops work. The kernel was compiled from the latest sunxi-devel branch 
of linux-sunxi repo.

Ifconfig says that wlan1 is running, but all operation fails by timeout.

# iwlist wlan1 scan
wlan1     Interface doesn't support scanning : Connection timed out

# time iwconfig wlan1
wlan1     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          
real    0m4.999s
user    0m0.000s
sys     0m0.010s


Each second two messages appears in dmesg:
brcmfmac: brcmf_sdiod_regrw_helper: failed to read data F1@0x0a020, err: 
-110
brcmfmac: brcmf_sdio_dpc: failed backplane access over SDIO, halting 
operation 

More related messages:
brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout
brcmfmac: brcmf_fil_cmd_data: Failed err=-110
brcmfmac: brcmf_cfg80211_get_tx_power: error (-110)
brcmfmac: brcmf_do_escan: error (-110)
brcmfmac: brcmf_cfg80211_scan: scan error (-110)

The command rmmod brcmfmac never finishes.

Also, when wifi stops work, mmc error messages repeat in dmesg:

When wifi module is unloaded there are not any mmc errors.

I use dd if=/dev/zero bs=64k command via ssh to test wifi.

I can also check other versions of kernel.

Best,
