Linux Wheezy just compiled 3.2.65 kernel does not see UUID of my 1st partition anymore.

Hi all.
Could you read everything please : i try to give all the details.

I'm on Debian wheezy and i just compile a knew kernel comming from debian
Distribution.
In fact it is the last dpkg update kernel source 
for the stable wheezy.

uname -a gives:
Linux Amd64 3.2.65 #1 SMP Mon Feb 16 22:04:41 CET 2015 x86_64 GNU/Linux

Unfortunately it does not sees my root partition / if I tell grub2
to search it by UUID.

Note that i have my /boot partition (where leaves the kernel and so)
different from the / partition (linux system and linux tree entry).

On boot i have a message like:
blkid : cannot find UUID=xxxxx or something like that when booting
by /dev/sdb5 : possibly that uuid is red in /etc/fstab.
But trying to boot with uuid give a kernel panic
unable to boot on (0,0) or something like that.
Note also the i did compile kernel WITHOUT initrd. 
I notice that the install process of the kernel continues
to build an initrd in anyway even if my kernel options
say that i dont want it: what the hell?
Are there any changes?

So I took of the initrd and could see that kernel boots
whithout (and really faster).
The fact to boot WITH initrd does not change anything
and gives also a panic.

May be this could also be a trick with /etc/fstab or grub.cfg
my /etc/fstab declare boot partitions with uuid.

I am using grub2 and i tried with old grub2 config before installation
of my knew kernel but it gives the same result.

When i run update-grub2, the grub.cfg writen does not tell the
kernel to boot with UUID but with /dev/sdb5 which is 
/ partition ... but it does for my old kernels.

And il works but I don't like that: not dynamic.

In general, is there a way to trace this with grub2?
I suppose on the early stage, kernel does not sees
/boot/disks/by-uuid 

Did i forget a kernel option or .... ?

I got a lot of pain reading grub2 doc because it's not my
natural langage. And there are many things confused for me.

Who could help me?

Thank you very much in advance.
Pim.
