Bug Description

Binary package hint: linux-source-2.6.20

This is on up to date (as of 20070513) feisty system, x86.

When I comment the NoAccel "true" line in /etc/X11/xorg.conf, the computer freezes (no ping, no keyboard/mouse reaction, need to reboot) after a few seconds to a few minute of use.

When the NoAccel "true" is present, the computer is completely stable (no freeze/crash) but of course scrolling and moving windows around is quite slow.

From a remote ssh on console I was lucky to get oops message the last time I tried to enable Accel, see below for details.

Let me know if there are things I could try.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

As feisty is now end-of-life we will not be trying to fix this bug in that release. Therefore moving this bug Won't Fix. If this bug is still present in the most recent Jaunty Jackalope 9.04 release - http://www.ubuntu.com/news/ubuntu-9.04-desktop - please file a new bug with any logs. Thanks!
