I've seen others with this message, but no solutions. 'dmesg' shows this right after I modprobe the module for my built-in wireless card. I've also noticed very bad performance by the card under linux, freezing my system for 1-2 seconds each time it has to communicate over the wlan (horrible for surfing). I'm guessing the two issues are related.. I'm using kernel 2.6.8.1 vanilla, with a Ralink rt2500 card, and kernel module compiled from the source provided by ralink. I posted a similar thread in the network forum before I noticed these messages from dmesg. Any help would be appreciated, no wireless = no linux, and I don't like windows

Check out this posting I made in the Ralink Forum ( http://61.222.76.235/phpbb2/viewtopic.php?t=13) earlier today.
Some smart guys found out how to work around the problem, and I wrote this little how-to based on that information - In short: Just comment out the line that complains (kernel/softirc.c) and be happy. I experienced the same problem and solved it this way - no warranty that it works for you!
It seems the speed problems you describe are simply from writing so much into /var/log/messages all the time. It might be a good idea to cat /dev/null > /var/log/messages after this to save diskspace.
The steps may bei somehow too easy for gentoo users - half of the text would have been enough. Good Luck! 
To make the "patch your kernel" thing clear to everyone (hopefully Smile )
1.) go to your kernel sources dir
| Code: | | # cd /usr/src/linux |
2.) edit the kernel/softirq.c file
| Code: | | # nano kernel/softirc.c |
// (or use your favorite text editor)
3.) find line 136 which says | Code: | | WARN_ON(irqs_disabled()); |
(in nano, you can use ctrl+c to see your current position in the file)
4.) comment out the line
| Code: | | /* WARN_ON(irqs_disabled()); */ |
5.) Save the file (ctrl+o) and quit (ctrl+x)
6.) recompile the kernel
6.5) install the modules //to lazy to change all numbers
| Code: | | # make modules_install |
7.) install the kernel - copy it to the location you specify in your boot managers config
8.) reboot
9.) Enjoy, if this solved your problem, or bite your desktop (the real one, german saying) if it persists Smile
10.) Anyway, feel like a really l33t kernel hacker and apply at redhat or suse for a new job.
THANKS A LOT and RESPECT to those who found out about this in the RAlink Forum. [/code]

Awesome, thanks for the tip and the ralink forum link! It turns out someone just found a fix today for the ralink driver, rather than editing the kernel source.
