[driverloader] kernel oops on X11 shutdown with stk16 kernel

[Linuxant support (Jonathan)]

Hi,

since you have an issue with the Fedora Core 3 kernel we provide, please 
try with a fresh 2.6.9 kernel from http://www.kerne.org instead. To 
obtain a 16K stacks kernel, please apply the following patch to the kernel :
