According to your previous mail, the fault happen at the address instruction pointer =3D 0x20:0xffffff8040d2cc83 Your disassembled the stack instead. Please just do disass 0xffffff8040d2cc83,0xffffff8040d2cca0 in kgdb. But also, I want to see the backtrace and disassembly output from ddb. --HKLejDDV6gCqJAZ/ Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (FreeBSD) iEYEARECAAYFAkxpkgAACgkQC3+MBN1Mb4jwMgCg9z90HSPV3bShg6g3qHLvziQ4 MVAAn2PcgyHKrGios8KhLh1FaUXxA0tU =am9r -----END PGP SIGNATURE----- --HKLejDDV6gCqJAZ/--
