I'm currently running RH9 at a rawhide level of code, with the 2.6 kernel from Arjanv.

I have a Logitech Quickcam Pro 4000 that worked with the 2.4.21.x.nptl kernel.

This quickcam now works with the new kernel over all just fine. The only problem is i cannot load the pwcx (phillips decompressor) module.

Below are the results of when i attempt to load the module.

> modprobe -f pwcx
FATAL: Error inserting pwcx (/lib/modules/2.6.0-0.test3.1.31/kernel/drivers/usb/media/pwcx.ko): Unknown symbol in module, or unknown parameter (see dmesg)
> dmesg
/* snipped stuff */
pwcx: no version magic, tainting kernel.
pwcx: module license 'unspecified' taints kernel.
pwcx: Unknown symbol preempt_schedule
pwc Frame buffer underflow (21825 bytes); discarded.

I've talked to the dude who runs the phillips driver page and he says i need to run a kernel that is pre-emption enabled.
I've talked to Arjanv and he says that he doesnt plan on releasing a pre-emption enabled kernel.
I've never had any luck at all trying to recompile a linux kernel, beyond doing the "rpmbuild --rebuild kernel.x.src.rpm" type commands.

Is there a way to use the rpmbuild commands to enable preemption? Like maybe --define 'CONFIG_PREEMPT=Y' or something?

Or is it something totally different that i need to do to make this work? Any ideas?

Thanks!!!
