Need help with installing Qlogic SCSI driver

[stokes]

OK - I'm a reletive newbie to this sort of thing. I'm trying to install a qlogic scsi card on red hat 4 ES. So far I have installed the kernel source and created a symlink to the build directory:

up2date -i -f kernel-devel
ln -s /usr/src/kernel/`uname -r` /lib/modules/`uname -r/build

I've downloaded and compiled the driver which seemed to work fine, no errors encountered, but I'm unable to install the module. Im getting 'Invalid module format'.

# insmod qla2xxx.ko ql2xextended_error_logging=1
insmod: error inserting 'qla2xxx.ko': -1 Invalid module format

My kernel source is the same version as my kernel - originally I thought that might have been the problem.

Any help is appreciated :S
