Oops... not sure why.

["Russell Harmon" <eatnumber1@gmail.com>]

Hey all, just updated to 2.6.22.1, and have been getting the following
oops rather often in my dmesg. It eventually makes it so no programs
will start, and I lose internet connectivity and so have to reboot. I
have a centrino duo system running SMP.

I'm using SLAB.

Thanks
