The kernel versions for these are: - squeeze: 2.6.32.59 but with e1000e backported from 2.6.38 - sid: 3.2.23 - experimental: 3.5 > I'm reporting this issue with current sid with > experimental kernel running.

Bruce, Jeff, any ideas? Marc's full bug report is at <http://bugs.debian.org/684213> and the information relating to e1000e and this laptop model is quoted below. Ben.
