Re: Natty with Stock Linux 2.6.38 Awful - Custom 2.6.39-rc5 Great

2011-04-29 Thread Tony Atkinson 
Just to report back
I think my issues are hardware related, so haven't filed a bug

performance issues started up again on my custom .39-rc5 kernel after
about 2 hours use

I compiled a kernel.org .38 just to see, same as .39-rc5

I'm think my graphics card is overheating (it's only passively cooled),
and this is causing my issues

Just a simple question: are the base-packaging, debian-changelog,
defaults-config patch files already included in linux-images ?

To note, vanilla mainline builds are available, too, for precisely
this sort of regression narrowing; see
http://kernel.ubuntu.com/~kernel-ppa/mainline/.

You are going to want to file a bug report, and it sounds like you are
on the right track to narrowing down the problem, which will help a lot.
 Keep up the testing!

Natty with Stock Linux 2.6.38 Awful - Custom 2.6.39-rc5 Great

2011-04-27 Thread Tony Atkinson 
Hey ho,

I've been having serious performance issues with the stock Natty kernel

System:
- Intel core2 Duo (dual core)
- 4 GB RAM
- Nvidia GeForce 9500 GT

Symptoms:
- Programs that hit the disk a lot are stalling regularly for multiple
seconds (compiz dimmed) then coming back
- Very choppy (slideshow) Hi-def video
- General sluggishness of UI

Compiled Linux 2.6.39-rc5, just to test
and all these issues are gone

Just to be clear, this is a vanilla kernel from kernel.org
Using the natty .38 config, and all new kernel options set to their
default values

I'm thinking, either
a) some Ubuntu specific change in the Natty kernel is off
b) something in .39 has improved dramatically


I'm posting this here (as opposed to filing a bug) as I'm not sure
exactly what the issue is
Tomorrow, I'm going to be compiling a vanilla .38 kernel, to try and
narrow down exactly where the issue with the natty kernel is, but
thought I'd post here first, prior to filing a bug, just to make sure
this is not a known issue


Thanks
