Check /etc/sysconfig/network-scripts/ifcfg-eth1 for:
HWADDR=
If not set, set it. If set incorrectly, set it correctly.
Also check your firmware version:
# ls -l /lib/firmware
...
-rw-r--r-- 1 root root 191142 Mar 7 2006 ipw2200-bss.fw
-rw-r--r-- 1 root root 185660 Mar 7 2006 ipw2200-ibss.fw
-rw-r--r-- 1 root root 187836 Mar 7 2006 ipw2200-sniffer.fw
...
Symptoms are exactly as you describe. Workaround is to:
# ifdown eth1
# rmmod ipw220
# modprobe ipw2200
# ifup eth1
That should work every time, but indicates that the firmware may be bad,
or HWADDR is wrong in the ifcfg-eth1 file.
Good luck!
