I have a similar problem here. No crash up to now, but the very same "hang" for a few seconds on "ifconfig wlan0 down". Interestingly this does only happen after a normal boot - once I did a suspend and resume (S3), there is no hang anymore.

Hardware: Thinkpad T61p with Intel 4965 agn
Software: Debian Lenny x86_64 with vanilla 2.6.27 kernel

I remember having the same "hang" with older kernels, too.
