After (some) re-reading and comparing dmesg's of other colleagues with 
this hardware (hp dl 385) something wrong was happening with the irq 
mapping on my boxes (acpi?). Several upgrades of bios, other OS running 
on them before ... whatever. As a quick and dirty try i've erased nvram 
leaving behind all previous settings. As a result, boot process goes 
further ... and stop setting something about ipv6. I'll see more tomorrow.

Maybe this can also help on other systems with similar ciss controllers.

Regars,
Raul.
