Hello,
After turning tls/ssl on in Exim and installing dovecot (with pop3s
and imaps) I've been getting a panic:
kernel trap 12 with interrupts disabled
=46atel trap 12: page fault while in kernel mode
cpuid =3D 2; apic id =3D 06
fault virtual address =3D 0x104
fault code =3D supervisor read, page not present
instruction pointer =3D 0x20:0xc06730cd
stack pointer =3D 0x28:0xea1ddc90
frame pointer =3D 0x28:0xea1ddc9c
code segment =3D base 0x0, limit 0xfffff, type 0x1b
=3D DPL 0, pres 1, def32 1, gran 1
processor eflags =3D resume, IOPL =3D 0
current process =3D 5 (thread taskq)
It's always the same. Same cpuid, same pointers, etc...
I have:
dumpdev=3D"AUTO"
in /etc/rc.conf and:
options KDB
options DDB # debugging kernel
in the kernel and I'm still unable to obtain a crash dump. Hopefully
there is enough info in this email for a hacker to point me in the
right direction to debug this.
