I can't explain it, but I may have a less drastic work-around. I had a
similar glitch yesterday. I rmmoded the ipw2200 driver, and modprobed
it. It's been fine since.

I do have a lot of this:

Mar 1 20:25:51 dragon kernel: ipw2200: Firmware error detected. Restarting. Mar 1 20:25:51 dragon kernel: ipw2200: Sysfs 'error' log already exists. Mar 1 20:44:22 dragon kernel: ipw2200: Firmware error detected. Restarting. Mar 1 20:44:22 dragon kernel: ipw2200: Sysfs 'error' log already exists.

I wonder if it's related to suspending to memory a lot.


I don't think so. It appears to be a driver or firmware issue. As a workaround, try adding

    options ipw2200 hwcrypto=0

to /etc/modprobe.conf. It seems to drastically reduce the number of these errors.

If you are bold and want to try the latest drivers (which may fix the porblem), see http://www.ces.clemson.edu/linux/fc2-ipw2200.shtml.

Some fixes in the latest stable kernel update for ipw2200 (including the hwcrypto=0). Try it out.
