rr2640 + Xen 3.4 hangs at boot [SOLVED]

Finally, I have boot up the xen hypervisor with the Highpoint RocketRAID 2640x4 SAS/SATA controller card.

1. compile the dom0 kernel with rr26xx module built in. Or another way to say it, "using the driver as a kernel patch". I tested in kernel 2.6.18.8-xen.

Download the rr26xx driver source, uncompress it to rr2640-linux-src-v1.xx/. If it is v1.5 driver, you need to uncomment out two lines in inc/linux/Makefile.def, otherwise it couldn't find the make target "patchkernel":

patchkernel:
@sh $(HPT_ROOT)/osm/linux/patch.sh

Follow the driver's README to patch the kernel:

# cd rr2640-linux-src-v1.xx/product/rr2640/linux/
# make patchkernel KERNELDIR=<kernel-source-dir>

# cd /usr/src/linux-2.6.24
# make menuconfig

   # make
    # make modules_install
    # make install

Note: This approach assumes that you will cd into kernel src (i.e., /usr/src/linux-2.6.24) to run "make menuconfig". If you have the kernel build in a separate directory, and hit "make" in that directory, it will NOT WORK.

2. In the /boot/grub/menu.lst, I need to provide the parameter:

kernel /boot/xen-3.4.0.gz edd=off
