correction:
DEBUG_MEMORY_INIT _isn't_ expensive, but outputs only at debug log level, so of
limited end-user use
by far, the really smoking items here are:
X86_PAT
X86_MCE
- both of these are on per upstream defaults and Fedora 12-alpha and
rawhide for good reason

X86_MCE (Machine Check Exception) use cases/justification:
- David's laptop is running slowly with no indication why
-> before moving his workflow over to Microsoft Windows, he (spending
considerable time) rebuilds the kernel with CONFIG_X86_MCE after finding a tip

X86_PAT (Page Attribute Table support) use cases/justification:

-> he expe
I omitted to add, while it's possible to disable PAT support via booting
with 'nopat', it's not possible to enable this mechanism when compiled
out. If pathological cases are found, booting with 'nopat' is an

karmic kernel
On a different platform (Thinkpad T400 w/ Radeon HD 3470) with the
radeon stack, we see:
2.6.31-12-generic w/o CONFIG_X86_PAT
$ x11perf -movetree
80 reps @ 0.0094 msec (107000.0/sec): Move window via parent (4 kids)
$ x11perf -scroll500
5000 reps @ 1.2153 msec ( 823.0/sec): Scroll 5
I do agree that X86_PAT and X86_MCE should be set.
However on the more minor options (as upstream InfiniBand maintainer), I
think INFINIBAND_AMSO1100_DEBUG and INFINIBAND_IPOIB_DEBUG should
continue to be set. These options enable runtime-controllable debug
output, and it is very useful to be abl
Oh and yes, INFINIBAND_NES should definitely be 'm' -- it is needed to
use Intel NetEffect 10-gigabit ethernet adapters. (Even just as straight
NICs)

Hi Daniel,
Thanks for the config review. The two config options you'd specifically
pointed out in comment #1 are currently enabled in the actively
developed Maverick kernel:
ogasaw...@emiko:~/ubuntu-maverick/debian.master/config$ grep -rn "X86_MCE=" *
config.common.ubuntu:4686:CONFIG_X86_MCE=y
This bug report was marked as Incomplete and has not had any updated
comments for quite some time. As a result this bug is being closed.
Please reopen if this is still an issue in the current Ubuntu release
http://www.ubuntu.com/getubuntu/download . Also, please be sure to
provide any requested in
Hi Leann - thanks for the input. I have conducted a review of Maverick's
2.6.35 kernel (based on 2.6.34) configuration options at:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/589439
It would be impractical on both sides to raise these as separate LP
bugs, so better than no bugs at all ;-
Can you confirm that the nopat kernel command line option was enabled
for the 9.10 release.
