7.7. Well, it seems that with the original onboard raid controller the bug didn't trigger... the controller was swapped with the lsi logic by my supplier because it fails badly with raid-5 arrays (hw/fw related issue) I also tried the original broadcom driver version 7.3.5 with similar results...
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!
