Stale modules (i.e. compiled for a > different kernel than the one you're running) will cause problems. All modules are up to date. This LOR popped up after installing from a resume buildworld. After blowing away /usr/obj, make cleandir twice in /usr/src and rebuilding and reinstalling world+kernel, it and the others still pop up, especially after any of these commands: # dhclient fxp0 # ntpd -q % fetchmail (only at startup, not after wakeup) Browsing in links does _not_ trigger a LOR. > Kris Regards, Rene --=20 "It won't fit on the line." -- me, 2001 --U+BazGySraz5kW0T Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQFCSrZPvz70qa4zXcwRAuILAJ47Kz2TeT9/Gypju0wPoabfjXGxcQCfc3xu 5N4hslUsWIzx7ogkDGthzfw= =yJFI -----END PGP SIGNATURE----- --U+BazGySraz5kW0T--
