This is most probably a transient problem: dstat=0x80: DMA FIFO empty (that's ok) sist =0x04: Unexpected Disconnect (but that's a problem ...) The ATN line is asserted, and the last bus phase appears to have been a DATA OUT. > Aug 2 10:29:26 isdn /kernel: script cmd = 800c0006 > Aug 2 10:29:26 isdn /kernel: reg: da 00 80 13 47 08 00 1f 01 08 80 00 80 00 0e 02. > Aug 2 10:29:26 isdn /kernel: ncr0: restart (ncr dead ?).
