I found the culprit. This is not related to the linux-pm tree but with
net-next.
The following patch introduced the issue.
commit 6bdb7fe31046ac50b47e83c35cd6c6b6160a475d
Author: Amerigo Wang <amwang@xxxxxxxxxx>
Date: Fri Aug 10 01:24:50 2012 +0000
netpoll: re-enable irq in poll_napi()
napi->poll() needs IRQ enabled, so we have to re-enable IRQ before
calling it.

AFAICS, it has been fixed by commit
072a9c48600409d72aeb0d5b29fbb75861a06631 which is not yet in linux-pm-next.
I fall into this issue because NETCONSOLE is set, disabling it allowed
me to go further.
Unfortunately I am facing to some random freeze on the system which
seems to be related to CONFIG_NO_HZ=y and CONFIG_CPU_IDLE=y.
Disabling one of them, make the freezes to disappear.
Is it a known issue ?
Thanks in advance
