PROBLEM:  (CLD ZPOBC0559)                 (Patch ID: OSF425-201)
********
This patch fixes a problem that occurs on a system running ATM. The system
panics with a "kernel memory fault" due to a simple lock time violation.
Prior to the crash, the pvc flag is observed as stale on a permanent virtual
circuit.  The crash occurs after the pvc is deleted with the following command:

# atmconfig -pvc .....

A sample stack trace is shown in the following example:

While running Classical IP over the lfa ATM driver, a kernel panic will
occur "simple_lock: minimum spl violation" if the following conditions
are true:
        1) The lfa driver is configured to use deferred interrupt
           processing (driver attribute "minimal_isr" is set to 1).
           Note:  This is the default for the V1.0.17 driver.
        2) lockmode 4 is being employed (generic attribute "lockmode"
           set to 4).
On systems where lockmode 4 is not employed, a cpu would hang instead.
