Running CURRENT and ran 'pptpclient x.x.x.x LABEL' to setup my VPN connection. On a CURRENT from Nov 8th, that rebooted my machine, but with CURRENT, after an ifconfig or two (just viewing ifconfig output), i got: Unread portion of the kernel message buffer: Memory modified after free 0xc3555aa0(28) val=0 @ 0xc3555aa0 panic: Most recently used by in6_multi 9 0xc06983ff in panic (fmt=0xc090504a "Most recently used by %s\n") at /usr/src/sys/kern/kern_shutdown.c:539 #10 0xc07eaebd in mtrash_ctor (mem=0xc3555aa0, size=-1056755712, arg=0x0, ---Type to continue, or q to quit--- flags=2) at /usr/src/sys/vm/uma_dbg.c:137 #11 0xc07e908b in uma_zalloc_arg (zone=0xc1061d20, udata=0x0, flags=2) at /usr/src/sys/vm/uma_core.c:1850 #12 0xc068e6e2 in malloc (size=32, mtp=0xc0973280, flags=2) at uma.h:275 #13 0xc06be2da in ioctl (td=0xc38f7c00, uap=0xde8ebd04) at /usr/src/sys/kern/sys_generic.c:580 #14 0xc086fffa in syscall (frame= {tf_fs = 59, tf_es = 59, tf_ds = 59, tf_edi = -1077943076, tf_esi = 134544752, tf_ebp = -1077943000, tf_isp = -561070748, tf_ebx = -1077943072, tf_edx = -1077943136, tf_ecx = -1077943104, tf_eax = 54, tf_trapno = 12, tf_err = 2, tf_eip = 672362955, tf_cs = 51, tf_eflags = 642, tf_esp = -1077943284, tf_ss = 59}) at /usr/src/sys/i386/i386/trap.c:1003 #15 0xc085c6cf in Xint0x80_syscall () at /usr/src/sys/i386/i386/exception.s:200 #16 0x00000033 in ?? () Previous frame inner to this frame (corrupt stack?) The syscall(), from what I remember in my DDB session was being called by ifconfig. With INET6 disabled, no panic(), but wasn't having much luck with pptpclient. I'll leave that issue out for now though since it seems there's something wrong. I can help debug, I've not been doing much FreeBSD work lately, so need a couple of pointers on what's useful that I could do. I imagine this address would likely change upon reboot.
