    SubjectDriver crash when changing a function from external to internal linkage
    I have an ISR which schedules a tasklet to handle an interrupt.

    The tasklet is function A, which calls function B, which calls function C.

    When all of A, B, and C have extern linkage, there's no problem.
    However, when B is declared static, the driver crashes, and hangs up the
    machine. The driver only crashes if C contains any code; if it's just an
    empty function then there's no problem.

    Any thoughts on what the problem is here? This is x86_32/PAE,
    2.6.18-53.el5PAE, gcc 4.1.2 (Red Hat 4.1.2-46).

    Thanks -
