Thank you.  This is quite helpful.

I see my "sleeping 15s ..." message... twice.  The first occurs just 
after "wi0: Lucent Firmware: Station 8.10.0".  The second occurs just 
after "Doing initial network setup: hostname ipmon ipfilter."

Back to the original problem: wi0 doesn't get an IP address.  
dhclient is running.  /var/dbh/dhclient.leases has the expected 
values (I deleted it before rebooting).

I have similar.  However, If I remove the card, dhclient is not 
killed but wi0 disappears from the ifconfig output.  If the card is 
then inserted, I don't see the "sleeping 15s" message.
And ifconfig still doesn't show a wi0 interface.

This is what I see:

[root at laptop:~] # wi0: timeout in wi_seek to fc80/0; last status ffff
wi0: timeout in wi_seek to fc80/0; last status ffff
wi0: detached
pccard: card removed, slot 0
Apr  7 17:57:56 laptop /kernel: stray irq 3
Apr  7 17:57:56 laptop dhclient: send_packet: No route to host
Apr  7 17:57:56 laptop dhclient: receive_packet failed on wi0: No 
route to host

In fact, unless wi0 is inserted before booting, I can't get it to 
work.

Possible clues: During the boot process, the "ifconfig wi0" 
information appears on the screen but without an IP address, and with 
the wrong channel (and "status: no carrier").  The SSID, wep info 
etc, are all there.

Clues please?
