Re: RH 2.6 64-bit experience needed (..duplicated ioctl32 handler )

I believe, if my memory is working right, that is the same
problem we saw on s390x which caused us to change the

      #define __SID ...

in LiS/include/sys/gnu.stropts.h and LiS/include/sys/stropts.h
If you look at the patch(es) I sent, they redefine __SID to have
a higher starting/base value to avoid a collision with some
linux kernel defined ioctl.  If you change __SID your LiS dependent
drivers have to be recompiled with that same __SID.

If you took the __SID part out of the patch, try putting it
back in.  I don't have easy access to a RHEL4-x86_64 system
right now, but I should be able to check this out more early
next week if that suggestion does not help.
