Yo! Admittedly it's silliness, but I tried it anyway... $ mii-tool eth1.10 --> instant kernel panic System recovers and runs normally after, though, and only has problems later when VLAN interfaces should be taken down at shutdown. This is kernel 2.6.8 (with Debian patches), on a via_rhine card. I lack the time and skill to debug this, but (I'm guessing here) it might be both easy to reproduce and relatively easy to fix. greetings -- vbi -- Oops
