in more this do not works:


# athmem=`lspci -vd 168c: |sed -n 's/.*Memory at \([^ ]*\).*/0x\1/p'`

# echo $athmem 
0xfbcf0000

# ath_info $athmem
sleep_ctl reg 000005df   reset_ctl reg 00000000

Comment 2 John W. Linville 2012-01-18 18:32:14 UTC 
I am told that the device in question is an ath9k device.  That probably explains why ath_info doesn't work... :-)
Comment 3 MERCIER Jonathan 2012-01-18 19:15:41 UTC 
oh ok i was think is a genereic tool for atheros wifi card, sorry.

Maybe you're hitting this regression:

c1afdaff90538ef085b756454f12b29575411214 upstream kernel

ath9k: fix going to full-sleep on PS idle
