Subject: xl2tpd: Version 1.3.6+dfsg-4 freezes all system Package: xl2tpd Version: 1.3.6+dfsg-4 Severity: important
Dear Maintainer, After system upgrade, xl2tpd version was updated to 1.3.6+dfsg-4 from 1.3.6+dfsg-3. Now, when I start xl2tpd.service it causes complete freeze of my system (with and without X), so i had to use alt+sysrq+b to reboot the machine. When system booted, I tried to log in without starting xl2tpd and there was no freezes at all (so, I'm sure it's xl2tpd-related, maybe partially ppp-related (conflict?)). If I start xl2tpd without starting Xorg, there's messages like that (from /var/log/messages): --------- Dec 1 14:50:51 fatrat kernel: [ 329.842544] xl2tpd[2043]: segfault at 17c ip 08052de3 sp bf91f8e0 error 4 in xl2tpd[8048000+1e000] Dec 1 14:50:51 fatrat pppd[2133]: Plugin pppol2tp.so loaded.
