Bug Description

I'm only using the Intel southbridge raid, ICH10, so I'm suprised this is being an issue especially given your using a production linux kernel version. Seems to be related to MD RAID being tainted by an external odule.

Anyway, this occurs everytime I boot.

Having a bit more time to go through these logs, I see two problems:

1. The Intel ICH10 southbridge chipset raid. This is the most user visible problem where EXT4 filesystem problems are reported on each boot and will most often result in no boot taking place.

2. The Creative XFi Titanium sound card coupled to my tri sli NVIDIA GTX480s is having problems. Each of my three GTX 480s has an nvidia audio driver component to it and I dont think the supplied nvidia graphics driver actually contains the sound drivers to run these features in them. I have manually installed the properitary NVIDIA drivers. Result is kernel panics about sound problems.

Declining the Maverick specific nomination for now and leaving this open against the actively developed Ubuntu kernel (which happens to be Maverick at this time). Will re-open the nomination should a fix be narrowed down which we can confirm specifically resolves this issue in Maverick.

I am adding the regression-potential tag. I have done additional testing and I can confirm this MD RAID bug as a regression-potential because in 10.04 the issue does not exist. I can see my RAID 5 array no problems, as well as the non-raid SATA drive also connected through the Intel ICH10 southbridge.

I have removed the NVIDIA Fermi GTX 4XX / Azuntech Home Theatre HD sound issues from this bug report. Apport pulled that into the one bug automatically when it went through the bug reporting process. I have since discovered that an NVIDIA developer has provided details on resolving the NVIDIA Fermi chip audio problems in Ubuntu in bug 611810. Therefore I've removed it from here and left the MD RAID taint issue for this bug report.

@nullack, can you test whether this is still a problem with newer kernels? Your apport info shows you were running 2.6.35-19. The following change that was included in 2.6.35-20 looks like it might address your issue.
