Hardware:  IBM ThinkPad 770Z, IBM Turbo 16/4 Token-Ring PCMCIA adapter

After upgrading from Red Hat 6.2 to 7.0, inserting the Token-Ring adapter
fails with the following error message:

    ibmtr_cs: register_trdev() failed
    tr0: Unexpected interrupt from tr adapter

I have verified that the ibmtr_cs line in /etc/pcmcia/config.opts has not
been changed.

I have rebuilt the kernel RPMs with PCMCIA 3.1.20 and the latest Token-Ring
driver (http://www.ibmtr.net/download/ibmtr_cs-2.2.17-2.tgz), and it works
once the ibmtr_cs line is completely commented out of
/etc/pcmcia/config.opts.

(BTW, the sard patch has a reference to the pcmcia-cs-3.1.19 directory
"hardcoded" in it.  To avoid this problem in the future, I suggest that the
kernel build process be changed to rename
$RPM_BUILD_DIR/linux/pcmcia-cs-%{pcmciaver}/ to
$RPM_BUILD_DIR/linux/pcmcia-cs/.  This would allow large patches such as
the sard patch to be "independent" of the PCMCIA version.)
