Can you make sure you have a complete debugging kernel with WITNESS=20 enabled? Setting debug.iwi could also reveal what's going on. =20 Unfortunately it's only a sysctl, not a tuneable, so you'd have to change=20 the default in sys/dev/iwi/if_iwi.c line 88 by hand and recompile your=20 kernel/module. By the way, are you using iwi built in or as a module? =20 Do you load it via loader.conf or on demand from rc.d/*? =2D-=20 /"\ Best regards, | mlaier@freebsd.org \ / Max Laier | ICQ #67774661 X http://pf4freebsd.love2party.net/ | mlaier@EFnet / \ ASCII Ribbon Campaign | Against HTML Mail and News --nextPart2234291.MziykGeSRY Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (FreeBSD) iD8DBQBFFtI7XyyEoT62BG0RAhfBAJ4rJsdDkRwz0YiRjURENjj+LdH9agCeNThc HWmwmcb2j561KpN2a7i76Eo= =JDPq -----END PGP SIGNATURE----- --nextPart2234291.MziykGeSRY--
