 The first thing should be a kernel built with DIAGNOSTIC. If conn
 is NULL, the assertion will trigger.
 
 ISCSI_DEBUG is enabled by default, you just have to configure
 the level with sysctl. A level of 15 will trace CCB usage, but
 that generates lots of output, but if the error still appears,
 you can probably see where things go wrong.
