I made some tests again, switching back to the onboard dual aic7902 scsi controller (non raid) the tg3 dont hung anymore. I just noticed the IRQ mappings change between the two settings. The Broadcom eth get always the IRQ #25, the two onboard scsi controllers get #24 and #25 (shared with the eth, is it harmful??) but the megaraid driver gets the IRQ #28 I think it is something IRQ related because if the eth hungs but the kernel is still running I see more than 140000 irq per second with "vmstat". Hope it helps better!
