I got the same error message installing a self-compiled bristuff on a system using a HFC based ISDN card.
The problem turned out to be that the Hisax modules were loaded for the ISDN card, which prevented the zaptel driver from loading for the same card. The (temporary) solution was to remove the Hisax drivers from the kernel module directory. -- Installing zaptel-modules let ztcfg to: ZT_SPANCONFIG failed on span 1: non such device or address (6) https://launchpad.net/bugs/47626 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
