Architecture: i386
Machine: i386
>Description:
When 2 firewire hard drives are attached to a 3 port PCI firewire card, the kernel panic.
When one only enable one port, the machine boots properly.
The hardware work fine under the same configuration under linux which rules out
a possible hardware cause.

** booting with  both drives **
