How do you increase a kernel stack size?


Having an ongoing problem regarding my wireless card being installed, first i thought my fedora core3 system was not picking it up but i can see the card listed in the systeminfo, i have tried installed the dirvers via driverloader by linuxant but it states its not working and check kernel messages which i have which states stack size is 4k and driveloader requires 8k????



Help someone pleaseeeeeeeee

I believe you can select the kernel stack size when you compile you own kernel.
This is a nice exercise for when you have lots of sparetime to try different stuff and learn even more :-)

In the kernel configuration under Kernel Hacking on the main menu there is an option for Using 4kb for kernel stacks instead of 8kb. You don't want to use that option. You'll probably have to custom build a kernel unless Fedora provides a binary kernel that has that option disabled.

In the 2.6 series of kernels they introduced a new option to lower the kernel stack size by 4kb. Without getting into details, this is better for some things, but initially some drivers had problems with it (mainly things like the nvidia drivers). Most drivers I've heard of that had problems with this have since been fixed.

Anyway, your going to have to compile a new kernel for you system. The best way to do that is to download the Fedora 2.6.10 kernel package. This should have all the normal fedora options already in it. Install that rpm. It should be put in the /usr/src directory. Then follow the kernel compile howto from this site and remove the 4k kernel option I described in my first post.
