We just found and fixed a bug in the portalmem dereference() code that caused a kernel panic in the driver, so I published new packages for Connectal. Version 15.07.4 is available for Ubuntu (Precise through Vivid) and for Debian Wheezy.
This same problem existed in the zynq drivers, so I pushed new binaries for the zedboard, zc706, and zybo:
I got a warning about file size when pushing that, so I'll switch to using github's releases mechanism.
