Public bug reported: Ubuntu freezes during kernel boot on my Acer TravelMate 5720 Notebook. No ubuntu logo, loading screen etc. The kernel with this problem is 2.6.32. Via grub I can boot 2.6.31 where the problem does not occur, the PC boots normally.
I can also boot with 2.6.32 kernel, if I set the boot parameter acpi=off uname -a: 2.6.32-20-generic #29-Ubuntu SMP Fri Apr 9 20:35:55 UTC 2010 i686 GNU/Linux ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: linux-image-2.6.32-20-generic 2.6.32-20.29 Regression: Yes Reproducible: Yes ProcVersionSignature: Ubuntu 2.6.32-20.29-generic 2.6.32.11+drm33.2 Uname: Linux 2.6.32-20-generic i686 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.21.
