Hi all, I had this problem in the morning so I had to restar ser again to make it work.. May 2 12:00:45 dns2 kernel: Zapata Telephony Interface Registered on major 196 May 2 12:00:45 dns2 kernel: No ISA tormenta card found at d0000 May 2 12:00:45 dns2 kernel: Zapata Telephony Interface Unloaded May 2 12:00:45 dns2 insmod: /lib/modules/2.4.20-8smp/misc/torisa.o: init_module: Input/output error May 2 12:00:45 dns2 insmod: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters. You may find more information in syslog or the output from dmesg May 2 12:00:45 dns2 insmod: /lib/modules/2.4.20-8smp/misc/torisa.o: insmod char-major-196 failed I'm not really confident with SER so anyone who can explain me what the problem can be? maybe there's a module that cannot be loaded? please help me thanks Giuseppe
