Bug Description

Description: Ubuntu 10.10
Release: 10.10

The latest Lucid 2.6.32 and latest Maverick 2.6.36-rc7 kernels perform at top performance when I hibernate. I can hibernate in 15 seconds flat. The current Maverick kernel 2.6.35-22-generic hibernates at the near 2 minute mark. Resuming across all kernels is the same at 15 seconds.

this is my current cmdline

BOOT_IMAGE=/boot/vmlinuz-2.6.35-22-generic root=UUID=3fc3b475-04dd-4ed4-9c3a-842580b40bf6 ro verbose no_console_suspend nomodeset rootflags=data=writeback

I have no idea how to put the verbosity up and checking hibernate.log I am not sure where the problem is. This is all I have in that file right now

I upgraded to the pre-proposed kernel here ppa:kernel-ppa/pre-proposed (2.6.35-23-generic) and the hibernation slowdown is not there. I tried booting into my last newest kernel where the problem is bad *but* I couldn't get my desktop up for some reason. I didn't try to run apport-collect 658347 in the terminal, is it possible?

Hi Victor,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 658347

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
