It seems it is loading the symbols of the modules for the old kernel. As devfs is not a module, it shouldn't matter here. ---snip--- (kgdb) l *devfs_ioctl_f+0xf0 0xffffffff80346dd0 is in devfs_ioctl_f (/space/system/usr_src/sys/fs/devfs/devfs_vnops.c:757). 752 error = copyout(p, fgn->buf, i); 753 td->td_fpop = fpop; 754 dev_relthread(dev, ref); 755 return (error); 756 } 757 error = dsw->d_ioctl(dev, com, data, fp->f_flag, td); 758 td->td_fpop = NULL; 759 dev_relthread(dev, ref); 760 if (error == ENOIOCTL) 761 error = ENOTTY; ---snip--- I would assume I can not print anything from there with my core-dump, as the backtrace is not usable.
