I am getting this issue on my new Acer laptop. The configuration is as follows:
* Linux 3.6 (linux-image-3.6-trunk-amd64) which is needed for the HD4000 graphics card * pm-utils 1.4.1-9 * An Atheros wireless card running with the atk9k driver 03:00.0 Network controller: Atheros Communications Inc. AR9462 Wireless Network Adapter (rev 01) And like for the original reporter, there is no 'wireless' directory in wlan0: $ ls -l /sys/class/net/wlan0 lrwxrwxrwx 1 root root 0 Nov 16 01:55 /sys/class/net/wlan0 -> ../../devices/pci0000:00/0000:00:1c.1/0000:03:00.0/net/wlan0 $ ls -l /sys/class/net/wlan0/ -r--r--r-- 1 root root 4096 Nov 17 21:01 addr_assign_type -r--r--r-- 1 root root 4096 Nov 16 01:55 addr_len -r--r--r-- 1 root root 4096 Nov 16 01:55 address -r--r--r-- 1 root root 4096 Nov 17 21:01 broadcast -r--r--r-- 1 root root 4096 Nov 17 21:01 carrier -r--r--r-- 1 root root 4096 Nov 17 21:01 dev_id lrwxrwxrwx 1 root root 0 Nov 16 01:55 device -> ../../../0000:03:00.0 -r--r--r-- 1 root root 4096 Nov 17 21:01 dormant -r--r--r-- 1 root root 4096 Nov 17 21:01 duplex -rw-r--r-- 1 root root 4096 Nov 17 21:01 flags -rw-r--r-- 1 root root 4096 Nov 17 21:01 ifalias -r--r--r-- 1 root root 4096 Nov 16 01:55 ifindex -r--r--r-- 1 root root 4096 Nov 17 21:01 iflink -r--r--r-- 1 root root 4096 Nov 17 21:01 link_mode -rw-r--r-- 1 root root 4096 Nov 17 21:01 mtu -rw-r--r-- 1 root root 4096 Nov 17 21:01 netdev_group -r--r--r-- 1 root root 4096 Nov 17 21:01 operstate lrwxrwxrwx 1 root root 0 Nov 16 01:55 phy80211 -> ../../ieee80211/phy0 drwxr-xr-x 2 root root 0 Nov 17 21:01 power drwxr-xr-x 7 root root 0 Nov 17 21:01 queues -r--r--r-- 1 root root 4096 Nov 17 21:01 speed drwxr-xr-x 2 root root 0 Nov 17 21:01 statistics lrwxrwxrwx 1 root root 0 Nov 16 01:55 subsystem -> ../../../../../../class/net -rw-r--r-- 1 root root 4096 Nov 17 21:01 tx_queue_len -r--r--r-- 1 root root 4096 Nov 16 01:55 type -rw-r--r-- 1 root root 4096 Nov 16 01:55 uevent Note that one side-effect of the power-save mode is frequent high latency when using ssh. So it would be nice to at least avoid that while on A/C power. For now I simply removed the 'wireless' directory check from the script. -- Francois Gouget <fgou...@free.fr> http://fgouget.free.fr/ A particle is an irreducible representation of the Poincaré Group - Eugene Wigner
