See www.linuxtr.net for the latest greatest set of bugs. Generally
speaking the biggest problem that I've seen (with ibmtr) is that
if you pull your connection from the wall the 2.0.x series of
kernels would generally not recover.
This has been fixed in the latest version of ibmtr and the driver
should now recognize when the link cable has been detached.
There are some laptops that don't want to work with the Olympic Cardbus
adapter, for some reason the driver never sees the open interrupt from the
card. I don't think this is a problem with the driver, but with the Cardbus
subsystem, for some people this problem has simply gone away with a newer
kernel and I personally have never seen it on the laptops I've used in the
development of the driver (Sony Vaio Z505 and Dell Latitude CPx500).
