Public bug reported:

On my old laptop (ThinkPad T40p, ipw2100) if I had the following in
/etc/network/interfaces then after a suspend/resume cycle the network
card had re-associated with the AP and network was usable again:

auto eth0
iface eth0 inet dhcp
        name home
        wireless-essid Burton
        wireless-key [snip]

However my new laptop (ThinkPad X60, ipw3945) with an identical
configuration doesn't do this.  After resume it's unassociated:

$ iwconfig eth0
eth0      unassociated  ESSID:off/any
          Mode:Managed  Frequency=nan kHz  Access Point: Not-Associated
          Bit Rate:0 kb/s   Tx-Power:16 dBm
          Retry limit:15   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

sudo ifdown eth0 && sudo ifup eth0 brings the network back, but I'd
prefer not to have to do this every time I resume.

Note: the original reporter indicated the bug was in package 'linux-
image-2.6.15-26-686'; however, that package was not published in Baltix.
