I run both too.  But, I have found that things are occasionally not ok,
which I think is about the driver, and it manifests by wpa_supplicant
not configuring a key.  Once the network works dhcpcd has been flawless
for me.

and that works?  I would try '/etc/rc.d/dhcpcd restart' instead.

that seems odd; wpa_supplicant is just about configuring WPA2 keys.

That seems like a sign of another bug.  I have often restarted
wpa_supplicant with ifconfig down/up, to work around what I think are
driver or other bugs (urtwn, 10 year old macbookpro), but never seen a
panic.

I have it configured to just negoiate the WPA2 session key.
