Problem: Asterisk on a Mini-itx board working fine. Plugged in USB drive, then X100p and soundcard died. 2 other x100p's died. Put * on a new box, ordered 3 new x100p cards. On the new box I get: ZT_CHANCONFIG failed on channel 1 for 2 new cards. On the old box I get: FXO PCI Master abort, with the remaining new card. Same error as before. I think the mini-itx is frying the cards. zaptel.conf: loadzone = us defaultzone=us fxsks=1 zapata.conf: cat zapata.conf [channels] signalling=fxs_ks context=incoming echocancel=yes echocancelwhenbridged=yes relaxdtmf=yes rxgain=1.5 txgain=1.5 immediate=no busydetect=no callprogress=no musiconhold=default usecallerid=yes ;callerid=asreceived cidsignalling=bell ;cidstart=ring callwaitingcallerid=yes callwaiting=yes threewaycalling=yes hidecallerid=yes I run: modprobe zaptel modprobe wcfxo ztcfg -vv cat /proc/interrupts* CPU0 0: 3579066 XT-PIC timer 1: 9097 XT-PIC i8042 2: 0 XT-PIC cascade 7: 0 XT-PIC parport0 9: 9533 XT-PIC acpi, Intel ICH 82801AA, eth0 11: 0 XT-PIC uhci_hcd 12: 62963 XT-PIC i8042 14: 5824 XT-PIC ide0 15: 11 XT-PIC ide1 NMI: 0 LOC: 3579048 ERR: 0 MIS: 0
