Dear all,

When I installed Red Hat ES 2.1(kernel 2.4.9-e.12) for my PC, 
the issue of NULL pointer dereference in ide_revalidate_disk() occurred.
If it understands about the root cause of this issue,
Please let me know your idea.

        if (DRIVER(drive)->revalidate)                  <=== here !!
                DRIVER(drive)->revalidate(drive);

It was drive->revalidate is NULL as a result of my debugging.
When is a function pointer set up?
I want to hear your opinion.

Regards
Haruo
