I just tried 2.6.6-rc1-mm1 (patched with mppe and iscsi), same problem. I compiled with CONFIG_DEBUG_DRIVER and CONFIG_USB_DEBUG, after booting, I activate the usb-dongle (Fn+F5 on the IBM T41p), then I run `hciconfig down' and `rmmod hci_usb', which triggers the problem I uploaded both the config and the whole syslog file from the boot until shutting down: http://mh57.de/~martin/config-2.6.6-rc1-mm1 http://mh57.de/~martin/syslog-2.6.6-rc1-mm1 > > Apr 12 12:07:48 localhost udev[22216]: removing device node '/dev/hci0' >=20 > Nice, glad to see udev is working for you :) I'm using udev 0.024-2 from debian, and it is working quite well :-) LLAP, Martin --2fHTh5uZTiUOsy+g Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFAhDa3mGb6Npij0ewRAoRiAKC4Q3VOfIc+nCzh7uczqrZQKZKLCwCgtOun UlCJKs0PYs+TiZzmI+tSAJE= =0vaA -----END PGP SIGNATURE----- --2fHTh5uZTiUOsy+g-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
