Subject: 2.6.25-rc4-git3: Reported regressions from 2.6.24

[Due to the lack of time for reviewing all of the email threads related to the
regressions marked as "unresolved" below, I might have missed some patches
fixing them. ?If you are involved in debugging/fixing any of them, please let
me know if I should update the list. ?Thanks!]

This message contains a list of some regressions from 2.6.24 reported since
2.6.25-rc1 was released, for which there are no fixes in the mainline I know
of. ?If any of them have been fixed already, please let me know.

If you know of any other unresolved regressions from 2.6.24, please let me know
either and I'll add them to the list. ?Also, please let me know if any of the
entries below are invalid.

Not a regression, and the patch is not required. The OOM was caused by
something specific to my system, and it's been resolved.

Peter reverted the load balance patch and 2.6.25-rc4 accepted the reverting patch.

With kernel 2.6.25-rc5, volanoMark has about 6% regression on my 16-core tigerton. If I apply
patch http://lkml.org/lkml/2008/2/20/83 which fixes the tbench regression issue, volanoMark
regression becomes about 4%.

I tried to bisect down which patch caused the last 4%, but found it's very hard. One thing
is many patches depend on the reverted patches. The other thing is I find the testing result
isn't stable since 2.6.25-rc1. The result variation might be more than 15% sometimes. I ran the
testing against the same kernel for many times to get the best result.

I also tried to tune some sched_XXX parameters under /proc/sys/kernel, but didn't get better result
than the default configuration.

Above regression exists on the 2.93GHz 16-core tigerton. With the less powerful 2.40GHz 16-core
tigerton, the regression is less than 1%, but result is not stable and results of many runs might have
about 15% variation.

On 8-core stoakley, the regression is about 1%.

Sorry for the late update.

No problem.

Thanks for the update, I added the new information to the Bugzilla entry.

However, since the regression is still there, I don't think we can close it.

2.6.25-rc6 includes the latest patch and I tested 2.6.25-rc6 on my 16-core tigerton. The
issue is fixed. Pls. close the bug report.
