After compiling the driver I get: [root@testmonkey linux-2.6]# insmod drivers/scsi/ciss.ko insmod: error inserting 'drivers/scsi/ciss.ko': -1 Invalid module format [root@testmonkey linux-2.6]# gcc --version gcc (GCC) 4.1.2 20071124 (Red Hat 4.1.2-42) [root@testmonkey linux-2.6]# uname -r 2.6.26 I built inside the tree.
