After recompiling my kernel (cvsup from about jan 13-97) with: FreeBSD global2000.net 3.0-CURRENT FreeBSD 3.0-CURRENT #0: Jan 14 12:50:25 EST 1997 eagriff@global2000.net:/usr/src/sys/compile/EAGRIFF i386 I use cu most of the time to dial for pppd, I dial, then ~! to shell. I then pppd /dev/cuaa0 38400 , and usually no problem, but since yesterday, It sig 11's, and off to ddb. what I am finding is _pppsioctl+0x17 cmpb something(%edi) after checking the registers, %edi is NULL. at first I paniced out. Then I found that set $edi $ebp would signal 11 once w/'c', and then come back up on a second set/c . At this point netstat -r shows all connections fine and the system is running fine. With a little digging, I found pppsioctl in /sys/net/if_ppp.c . I only have defaultroute in my options file, localhost in my /etc/hosts, and 2 nameservers in /etc/resolv.conf, and /etc/hosts.conf has hosts ; bind . My system is: Packard Bell BL510 60 Mhz Pentium 8 meg of RAM ide 1.2G Conner Pariferals ide 204meg Seagate ide cdrom Packard Bell 144AMSP Soundcard/Faxmodem/Ans system. And dialup ppp And here is my configuration. #beginning of sys/i386/conf/EAGRIFF # # EAGRIFF -- Eric A.

So is this a screwup I have in the pppd setup, or a bug? I hope I have givin enough information, and appreciate any response. Thank you in Advance Eric A. Griff
