Would you get the latest version from svn and see if that fixes the problem? Or, you could make the equivalent of this change:
http://linux-gpib.svn.sourceforge.net/viewvc/linux-gpib/trunk/linux-gpib/drivers/gpib/sys/ibinit.c?r1=1520&r2=1521
to your ibinit.c file (your version will be a kernel_thread call instead of a kernel_run call).
