I believe that this is the kernel thread which is used to handle the
"bottom half" code for device drivers.

What this indicates, I believe, is that your PCMCIA card's driver is
misbehaving. It's generating (or being fooled into generating) a
never-ending barrage of bogus device interrupts. This is forcing the
system to call the driver's bottom-half service routine over and over
and over... and so the CPU is never allowed to sleep when the system
is otherwise idle.

My guess is that the device driver you are trying to use isn't yet
fully debugged, and has some errors in it.
