I did `modprobe kvm' and then tried running a version of the KVM Qemu compiled for a different kernel. My mistake.

I'm not sure if this bug is in the kernel, wireless tools, or the ipw3945 driver, but I haven't changed the version of anything but the kernel. When I do `iwconfig eth1 essid foobar' something drops the last character of the essid, and a subsequent `iwconfig eth1' shows "fooba" as the essid. And it's actually set as "fooba", since I had to do `iwconfig eth1 essid MyUsualEssid_' (note underscore) to get on to my usual network. --Thomas Tuttle --OwLcNYc0lM97+oe1 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) iD8DBQFFbNNNgPpxLpYWreERAp8bAJ48VknjlZtCivvjjqlSiJdv4F2VgwCdHDax LfqCNa9zIE57eaaxcXP8DRc= =XSRk -----END PGP SIGNATURE----- --OwLcNYc0lM97+oe1-- - 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/
