Running on a Dell PowerEdge 1800 using Fedora Core 3 and a 2.6.16.16 kernel. I've built up this new kernel to roll out to our production systems and it's been in test on a PE1800 for a long time and working fine. However, the machine that it's been testing on has SATA drives. Yesterday I moved it to a production system, another PE1800 with SCSI drives and I'm getting an error Insmod /lib/modules/mptscshih.ko: -l unknown symbol The only differences I can find between the two machines is that the original build/test machine has gcc-3.4.4 and the new machine has gcc-3.4.2; but it looks like all the system libraries are the same and everything else. I even went so far as to move the entire source tree to this machine and do a make clean and rebuild and reinstall and I'm still having the same problem. What am I missing here??? Thanks! :b!
