In general you should not assume binary compatibility between kernel object modules in Linux. Security Notes Linux 2.2.19 contains significant security fixes as a result of third party testing and auditing.

Architecture Updates Alpha Remove a bogus printk in the OSF syscall error path. The DMI check for APM could end up running after APM started Updated A20 handler to 2.4 code.
