I'm seeing the errors below on at least two of the radios... DRHD: handling fault status reg 3 IPv6: ADDRCONF(NETDEV_CHANGE): sta600: link becomes ready sta604: deauthenticating from 00:a2:d2:b3:c3:01 by local choice (reason=3) DMAR:[DMA Read] Request device [04:00.0] fault addr 0 DMAR:[fault reason 06] PTE Read access is not set sta66: deauthenticated from 00:89:89:00:01:89 (Reason: 7) I'm low on ideas for how to debug this :P Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
