It could be many things...  a few questions first:

1) What wifi driver/version, and what kernel version?

2) what version of wpa_supplicant?  Do you have any custom patches?

3) What wpa_supplicant driver are you using, wext, a custom one, ...?

One theory is that the kernel driver itself isn't properly resetting the
state when the new configuration for SIOCSIWENCODEEXT comes in.  The
message "Association request to the driver failed" *could* indicate a
driver bug, but it's also reported when the driver just doesn't support
some of the less-necessary commands.  Giving the details above will help
diagnose that.
