OK..... have been burried in this and staring to get my head around it,
but have now hit a problem (apart from my wife starting to call me a
git!)
I'll try to reassemble my path here in case Ive done something stupid in
the earlier steps.
1. new virtual machine version 11.10 upgraded to 3.0.0-17 x86_64
2. grabbed every package via apt-get that seemed relevant
3. basic structure as per your script. git clone from kernel.org under linux.
git clone of ubuntu-natty
4. modified your script to grab from ubuntu-natty rather than oneiric
5. tried compiling with your script prior to bisect and all worked, producing
me .deb packages for 3.0.0-17
6. reconfigured virtual and threw 8 cores at it (forgot how long it takes to
compile a kernel.
7. changed to $HOME/linux-source/linux
8. git checkout mcebisect
9. git bisect start
10. git bisect good v2.6.35
11. git bisect bad v2.6.36-rc1
- complained about modfied files not commited (presuming from previous build)
12. git stash
-bisect completed with over 4000 / 12 to go.
13. up one level and ran your modified script.
-Compile failed.
14. back into ./linux
15. git bisect bad ##toss a coin - well almost. I saw lots of early comits in
the log for acpi and temprature, which I've always suspected re this bug.
figured that a bad guess would bisect next with early part included.... thereby
keeping it in the mix - easy to see test fail as the panic happens more quickly
than waiting to be sure that it hasnt.
- got same error regarding comits.
16. git stash
-bisect proceeded and worked.
17. Updated script with revision and comment and re-ran.
-Compile Fail again.
18. git clean, git reset, git checkout, git bisect start, git bisect good
v2.6.35, git bad 2.6.36-rc1, recompiled again (just to make sure it wasnt
something stuid I did in the setup.
- Compile failed as expected.
19. This time git bisect good # guess the other way
-Compile failed again.
Where to from here?
A couple of other aside questions:
1. Am I right that the the ubuntu git version is only there to grab the control
scripts?
2. Are there any issues / version problems grabbibg the ubuntu-package on my
3.0.0-7 system?
Thanks for your continued help.
