I have devoloped a PCI-X devicedriver in RHEL5(2.6.18EL) on x86_64 server.
I successfully compiled and inserted the driver.

Now Iam going to migrate the driver to RHEL4(2.6.9AS)on IA64 server.

Now My duobt is is there any processor based diferences between kernels.
Because Iam facing some compilation issues in memory based operations.

Thanks in advance.
