[driverloader] kernel oops on X11 shutdown with stk16 kernel

[Linuxant support (Jonathan)]

Hi,

please try with a fresh 2.6.8.1 kernel from 'http://www.kernel.org'. 
Before you compile this kernel, please apply this patch :

http://www.linuxant.com/driverloader/wlan/full/archive/linux-2.6.8-16kstacks.patch

You should make sure that the following configuration option is disabled

---
CONFIG_4KSTACKS
---

and you should enable the following option

---
CONFIG_16KSTACKS
---

Since you will now use a custom compiled Linux kernel, you will need to 
use the generic RPM package (if you do not already use it) that we offer 
on the DriverLoader download page at :
