Probably a PCMCIA not a block layer change - well I guess could be
either. I fixed a pile of PCMCIA bugs and also reworked the allocator for
pure PCI boxes so it didn't do various bad things.

Can you tweak drivers/pcmcia/Kconfig for config YENTA and make

        select PCCARD_PCI if PCMCIA !=n && !ISA   

instead do

	select PCCARD_NONSTATIC if PCMCIA !=n && !ISA

rebuild and re-test

The tracel looks like a block layer bug, but it would be nice to know if
its one that PCMCIA used it hide, or its in fact potentially something
else.

Do you have any other I/O port based PCMCIA device you can insert/eject
in that machine ?
