Hi,
I've a big problem with this controller with loader, i'm running a
RedHat in a Virtual Machine in Gentoo dom0.
When I try to write in a media, the Loader freeze randomly and dmesg return:

My grub.conf

title = Xen 3
root (hd0,0)
kernel (hd0,0)/xen.gz
module (hd0,0)/vmlinux-2.6.16-r1-xen0 root=/dev/cciss/c0d0p5
pci=routeirq irqpool max_loop=64 pciback.hide=(0f:08.0)

0f:08.0 it's a SCSI Controller PCI Id

Any ideas?
Thank you,
bye
