On omap, CONFIG_DEFAULT_MMAP_MIN_ADDR needs to be set to 32768 per kconfig notes

[Tobin Davis]

Currently, the default for x86/amd64 is for CONFIG_DEFAULT_MMAP_MIN_ADDR=65536 but according to the kconfig documentation upstream, armel should be set to 32768. On omap4, ac100, and mx5, this is correct, but on omap which uses the main kernel tree, this is not set properly.

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 903346

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Brad Figg (brad-figg)]

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

If the bug still exists, change the bug status from Incomplete to Incomplete. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.

 Thank you for your help, we really do appreciate it.

[Tobin Davis (gruemaster)]

Changing to confirmed as the kernel-autobot whining about missing logs is irrelevant to the bug filed. Only log output required is from "fgrep CONFIG_DEFAULT_MMAP_MIN_ADDR /boot/config-*".

Bots annoy me.

[Tobin Davis (gruemaster)]

This incorrect configuration has been verified to be in Natty (2.6.38), Oneiric (3.0) and Precice (3.2) release kernels. I would assume they are also in updated kernels for these releases as well. Please fix the Natty and Oneiric kernels in the next SRU release cycle. Precise can be fixed and uploaded with the next kernel build.

[Herton R. Krzesinski (herton)]

This bug is awaiting verification that the kernel in for Natty -proposed solves the problem (2.6.38-13.54). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-natty' to 'verification-done-natty'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[Tobin Davis (gruemaster)]

This is now correct on natty omap kernel (2.6.38-8.42-omap 2.6.38.2).

[Tobin Davis (gruemaster)]

And in Oneiric omap kernel (3.0.0-15.25-omap).
