I get kernel panic when reloading dahdi_cfg. The panic happens if dahdi/system.conf is allready configured. (see my attached system.conf)<br>
If dahdi/system.conf is unset, panic does not appear in this case. Perhabs it gives an indication.<br></blockquote><div><br>wcb1xxp is still in experimental state (and it does not exist in official dahdi svn at all). I'll let you know when it reaches production state.<br>
