Severity: important
Almost every time my system resumes, dhclient processes for the same
interface. Here is sample "ps" output after a suspend-resume cycle:

I also have connection problems that I think are related to this:
usually it will associate correctly with the WLAN and get an IP
address, but then the address is released after some seconds, and a
zeroconf address is set instead. The only way to fix is to kill the
dhclients manually and ifdown/ifup the interface.
wlan0 is a wireless interface managed by wpa_supplicant, in a WPA-PSK
network. The driver is iwl3945, this is a Thinkpad T61.
