Here is the end of the output on the guest console :

Still nothing wrong on Xen's one :

[ 0.000999] Console: colour dummy device 80x25
[ 0.000999] console [tty0] enabled
[ 0.000999] console handover: boot [xenboot0] -> real [hvc0]
Looking further in genetlink.c it seems that the freeze happens in :
synchronize_rcu (af_netlink.c:1540)
netlink_change_ngroups (af_netlink.c:1516)
genl_register_mc_group (genetlink.c:136)
genl_init (genetlink.c:800)
synchronize_rcu does not return after a very long time.
P.S: My first mail seems to be lost, sorry in advance if I double post.

I upgraded Xen to the last revision on the repository (21446) and
installed it. 2.6.31.13 kernel (branch xen/stable-2.6.31.x) do not hang at
boot time anymore (I have a 2.6.31.13 kernel on both Dom0 and pv DomU).
Netchannel2 is added (and appears in guest), nevertheless, I get a triple
fault from Xen's kernel when I try to start a dhcp client on the
netchannel2 interface. Here is the crash report on Xen's console :

nc2 is very untested, so it isn't surprising that you're having problems

I am trying to run a PV domU with netchannel2.
I used to achieve this with the kernel from xen/stable-2.6.31.x on linux-2.6-pvops repository. It does not work anymore, and does not seem to have any relation with netchannel2 (since I tried to remove it from my .config for testing purpose).
The kernel basically freezes while booting. No error displayed, neither on dom0 serial output (Xen in debug mode), or kernel one's. It just freezes after :
[ 0.000999] xen_balloon: Initialising balloon driver with page order 0.
[ 0.000999] SCSI subsystem initialized
[ 0.000999] usbcore: registered new interface driver usbfs
[ 0.000999] usbcore: registered new interface driver hub
[ 0.000999] usbcore: registered new device driver usb
[ 0.000999] PCI: System does not support PCI
[ 0.000999] PCI: System does not support PCI
I'm using the same kernel, with privileged domain configuration, as dom0 (2.6.31) on Xen-4.1 last revision.
I tried 2.6.32 and 2.6.33 for the pv domU, these ones achieve to boot, but do not support netchannel2.
Since I just want to have a pv kernel handling netchannel2, can anyone advise me a way ?
Thanks in advance,

Make sure you have "console=hvc0 earlyprintk=xen ignore_loglevel
initcall_debug" on your guest kernel command line to see if we can get
some idea of where its getting up to.

You're the first person I know to try nc2 in a pvops kernel, so I'm not
surprised you're encountering difficulties.
Thanks,

Here is the end of the output on the guest console :

[ 0.000999] calling genl_init+0x0/0xd8 @ 1
Still nothing wrong on Xen's one :
[ 0.000000] Detected 3000.022 MHz processor.
[ 0.000999] Console: colour dummy device 80x25
[ 0.000999] console [tty0] enabled
[ 0.000999] console handover: boot [xenboot0] -> real [hvc0]
Looking further in genetlink.c it seems that the freeze happens in :
synchronize_rcu (af_netlink.c:1540)
netlink_change_ngroups (af_netlink.c:1516)
genl_register_mc_group (genetlink.c:136)
genl_init (genetlink.c:800)
synchronize_rcu does not return after a very long time.
