I'm stuck in trying to bisect the problem.
I restarted from scratch and same result:

Here is what i did:

[5ed1836814d908f45cafde0e79cb85314ab9d41d] Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6

The EXTRAVERSION in the makefile at this point was "plain" 2.6.28 (which seems odd to me)

I renamed it to "-a1" and compiled kernel. 
Installed/rebooted.
after 16 hours (overnight) of no troubles i think it seemed stable:
reboot   system boot  2.6.28-a1        Fri Jan  9 16:54 - 09:29  (16:34)

version "-a2" was branded "ok" by me after 3 hours of heavy use:
reboot   system boot  2.6.28-a2        Sat Jan 10 09:31 - 12:37  (03:06)

Version "-a3" also got my blessing:
reboot   system boot  2.6.28-a3        Sat Jan 10 12:39 - 17:55  (05:15)

[a1941895034cda2bffa23ba845607c82138ccf52] [XFS] remove dead code for old inode item recovery

This time the Makefile EXTRAVERSION changed to "-RC6"
I was/am under the impression that i'm testing between 2.6.28-git2 and 2.6.28-git3
So why is the Makefile going this way back ? dazzled & confused.

"-a4" barfed

EXTRAVERSION went baack to "-RC2" ?!

"-a5" totally froze the machine (didn't catch anything on the netconsole)

So i interpreted that as a "fail"

Now "-a6" doesn't want to compile:

In the mean time i compiled/ran 2.6.29-rc1-git3 but it (as expected) barfed:

Al netconsole loggins are in my directory: http://www.dth.net/kernel/c3/

[F1] ;-)
