In 2.4.22, I get a repeatable oops by inserting a PCMCIA card using
the ray_cs driver (at which point everything's rosy), then downing
the interface and removing the ray_cs module. The message is
"unable to handle kernel paging request" and the kernel panics, so I
had to write down the oops, but I think I got the important data.

I interpret this to mean that everything after yenta_set_socket is
the attempt to handle a bad access in yenta_set_socket, so that
should be the proximal cause. I put some printks in
yenta_set_socket to find the exact location (I lack the skills to
understand the assembler code, but I can provide it), and this
changed the symptom to a hang with no oops after the printk just
before line 283:
exca_writeb(socket, I365_INTCTL, reg);
I also get the same result in 2.4.23-pre8.
I can reproduce the problem by booting my Toshiba Tecra 8100 to
single-user mode, starting cardmgr, inserting my WebGear Aviator 2.4
card, downing the interface, and rmmodding ray_cs. No modules other
than the usual PCMCIA ones were loaded.
I include below the kernel messages regarding PCMCIA and my .config.
As noted in my earlier message, I have used the stand-alone PCMCIA
drivers, including ray_cs, with no problems. I double checked that
they work in 2.4.22 configured the same way, except with the
in-kernel PCMCIA support turned off.
