None whatsoever.  Three people are reporting this and it's a drop-dead
showstopper for a 2.6.21 release so we just have to wait until someone
wakes up and thinks about it.

It would be very useful if one of the reporters could perform a git-bisect
search to identify the offending change, please.

I would dearly like to point you at a document or web page which describes
kernel-git-bisect-for-newbies, but afaik there isn't such a thing, which is
a huge failing.

I have one of those one-of-my-machines-wont-boot-2.6.21-rc*
and I expect that I'll try to use git bisect on it, in which case
I will also document it.

"Linux testers handbook" should be translated in a few weeks.

Here is a "git-bisect basics" movie :)

The topic should be "when CONFIG_HIGHMEM64G=y" imo.

I'll try to do my first bi-sect today.

Bisecting went well, after 13 compiles this commit was found:

a1f3bb9ae4497a2ed3eac773fd7798ac33a0371f is first bad commit
commit a1f3bb9ae4497a2ed3eac773fd7798ac33a0371f
Author: Roland McGrath <roland@redhat.com>
Date:   Fri Jan 26 00:56:46 2007 -0800

    [PATCH] Fix CONFIG_COMPAT_VDSO
    
    I wouldn't mind if CONFIG_COMPAT_VDSO went away entirely.  But if it's there,
    it should work properly.  Currently it's quite haphazard: both real vma and
    fixmap are mapped, both are put in the two different AT_* slots, sysenter
    returns to the vma address rather than the fixmap address, and core dumps yet
    are another story.
    
    This patch makes CONFIG_COMPAT_VDSO disable the real vma and use the fixmap
    area consistently.  This makes it actually compatible with what the old vdso
    implementation did.

Can you please double check this by trying with/without again -- sometimes bisects go bad.

> Can you please double check this by trying with/without again -- sometimes bisects go bad.
As requested I started to redo the test but now without git using 
kernel.org tars.
The results now are, still using the same .config:
linux-2.6.20.tar.gz   : bad
linux-2.6.20.1.tar.gz: bad (boot log equal)
linux-2.6.20.2.tar.gz: good
linux-2.6.20.3.tar.gz: good
(triple checked)

Really strange. Nilshar, please try these kernels too with:
COMPAT_VDSO=y
CONFIG_HIGHMEM64G=y

Re: [Bug 8040] Hang before INIT when CONFIG_HIGHMEM4G=y [Fix CONFIG_COMPAT_VDSO] <- Bad?

[Nilshar]

Correcting my previous message, and confirming Leroy's one :

> linux-2.6.20.tar.gz   : bad
> linux-2.6.20.1.tar.gz: bad
> linux-2.6.20.2.tar.gz: good
> linux-2.6.20.3.tar.gz: good

With :
> COMPAT_VDSO=y
> CONFIG_HIGHMEM64G=y

So problem have been solved with 2.6.20.2

Nilshar.

So you do have CONFIG_COMPAT_VDSO in your config, then?

Yes. 2.6.20 and 2.6.20.1 hang using this .config:
(Nilshar now also reported all is fine with 2.6.20.3)

Re: [Bug 8040] Hang before INIT when CONFIG_HIGHMEM4G=y

[Nilshar]

Hello,

I can confirm that the problem disappear when I disable Compat VDSO
support by setting CONFIG_COMPAT_VDSO=n.

Thanks Leroy.
