I am using kernel 2.6.33-rc7-00064-gac73fdd (latest git of linus' tree) and I have been experiencing an issue for more than a month now.
When the computer resumes from suspend (not hibernation), the RF killswitch seems ON (although dmesg does not say this, so it is just a deduction of mine). If I unload ipw2100 and reload it, the killswitch is disabled and wifi can work regularly.
Can you read the ipw2100 sysfs entry "
rf_kill" to confirm the rf kill state when this happens? Please also attach your dmesg.
It's always zero.
A recent dmesg is here:

sudo lspci -v:

Now I am experiencing a worse issue: the 2nd time I do this, reloading the module doesn't work anymore, and neither using my modified version of fsam7400 which did the trick in the past.
It appears to be an issue of 2.6.33 kernels. Shall I contact some kernel list?
You can include [email protected] if you want. If you can do some git bisect, that would be very helpful to identify the regression.
OK, I will go along the git bisect path if possible, but problem is really strange, since only reboots seem to fix it. Nobody else experiencing issues with ipw2100?
Best regards.
