Kernel linux 2.6.24-19-generic SMP causing lockups on Nvidia Cards

[Spydr4590]

I was using Ubuntu 8.04 just fine for a while now with Nvidia. I recently updated everything from Ubuntu to 8.04.1 and kept locking up afterwards. I thought maybe something went wrong so I downloaded Ubuntu 8.04.1 DVD and reinstalled everything. That did not help, as I kept having lockups any where from a min to an hour randomly with Compiz Fusion turned on. I want to point out I did not have this problem till I updated Ubuntu.

I went to Nvidia Linux Forums and tried some trouble shooting the only way I could get Compiz Fusion to work if I set the maxcpus to 1 for the boot up option. This defeats alot of purposes because my computer runs slower with one core. With deductive reasoning I figured out that it must of been the kernel update doing something to dual-cores. I downloaded the alpha 4 of Ubuntu 8.10 amd this fixed my locking up issues with Compiz Fusion turned on. The kernel version there is 2.6.26.5 However flash has a problem resizing with Compiz Fusion turned on.

I've went back to 8.04.1 but I can not fix my issues as I do not know how to upgrade or downgrade my kernel. I'm submiting this as a bug in hopes of it being fixed for 8.10 without flash issues.

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.

The Intrepid Ibex 8.10 Beta release was most recently announced - http://www.ubuntu.com/testing/intrepid/beta . It contains the 2.6.27 Ubuntu kernel. It would be great if you could test and verify if this is still an issue. The status is being set to Incomplete until we receive further feedback. Thanks.
