Segfault in VBoxRT when booting in cluster mode

[Pigi]

Hi,
I'm trying to setup a single node cluster on a Solaris guest running on a Linux host.
I've successfully installed Sol10_U9.
Everything was fine when running solaris and did a lot of test with containers, ipmp, zpool and so on.

After a while I decide to install SunCluster 3.2_u2 to experiment a bit with cluster environment (single node).
Installation went fine and so did sccheck and scinstall.
After rebooting in cluster mode I can see the guest that start up to cluster joining.
It starts configuring did devices and the hangs.
VBox Gui simply say "aborted" but I can see from dmesg those messages ( one for every failed boot ):
VirtualBox[5899]: segfault at 0 ip 00007f9b0a853c1d sp 00007f9b02a897b8 error 4 in VBoxRT.so[7f9b0a76e000+33e000]
VirtualBox[8393]: segfault at 0 ip 00007fcc20fd7c1d sp 00007fcc1920d7b8 error 4 in VBoxRT.so[7fcc20ef2000+33e000]
VirtualBox[8457]: segfault at 0 ip 00007fc8d6e6bc1d sp 00007fc8cb0357b8 error 4 in VBoxRT.so[7fc8d6d86000+33e000]

If I boot back in non cluster mode ( boot -x ) the guest starts correctly and I can't see any error.

Is there somethng to check ?

Vbox is 4.0.4. r70112 running on a slackware 13.1 x86_64 2.6.33.4 SMP
The host has 3Gb ram running on "Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz"
No problem during Vbox installation and kernel modules have built error free during installation

Thanks

Just as a side note, if I remove the scsi ( LSI ) controller and add a sata controller, the boot continues, so the problem is in scsi part ( or maybe in scsi reservation , when cluster comes up ).
