I was basically doing the same steps as the initial poster, I upgraded my Amilo M 7400 from wheezy-xfce to sid. With diffrent issues.
Wheezy was running fine with kernel 3.2.0-4-486. During dist-upgrade I noticed a previous kernel version kernel was installed (iirc 3.15-586). 1. On first boot I noticed the i9xx "pipe a underrun" error on the screen right after GRUB. 2. A minute on the desktop and the system went into S3 state. 3. resuming from S3 results in S3 state again after around 30 seconds tail -f syslog reveals constant pipe underrun messages I am able to boot, both the old 3.2.0-4-486 and the newly installed 3.1x-586 kernel into the sid desktop. But end up in S3 state as mentioned (both kernels). If there is time I'm going to run a clean testing install on this notebook. --- Sebastian -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
