Indeed. I thought that "trunk" meant "latest". I switched to it to get my Atheros wireless working. Anyway I can confirm that the problems don't occur with 2.6.32-5-amd64. I'm triple-booting (Debian-Lenny,Debian-Squeeze,Ubuntu-Lucid) so I tried Ubuntu and the problem's there too - with 2.6.32-5-amd64 - see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/629953 which I can only conclude is a regression. Please close this bug. Thanks, Philip
