Could also be a bug in the kernel module for your wireless device. It is
not uncommon to see funny driver errors after suspend/resume.

It looks like wpa_supplicant and associated code is doing what it is supposed
to be doing.

Timeout value of your dhcp client is controlled elsewhere such as
/etc/dhcp3/dhclient.conf for dhcp3-client.

Thanks, Kel.
