Bug Description

After upgrading to Kubuntu 10.04, kernel 2.6.32-21, the computer boots and runs extremely slowly.

It took about 30 mins to boot.

Reverting back to 2.6.31-20, the computer runs smoothly again, boot time is more like 60 secs.

I've attached a lspci and dmesg generated whilst using the 2.6.31-20 kernel, post-upgrade.

I'll provide as much information as possible, feel free to ask.

Hi David,

Sorry about not setting the package.

Have I provided enough info in the attachments?

I can't remember whether I sudo lspci or not, so it might not be complete.

Let me know if you need anymore info.

Hi Matt,

Thanks for the response. If you want to attach all relevant information, you can run "apport-collect 569883" when running 2.6.32. I'm not sure what is exactly necessary though, since I'm don't specialize in kernel bugs.

I assume you can reproduce the error with the 10.04 release today?
