Post subject:  R5.5 No sata_mv module
I'm having trouble with my Supermicro AOC-SAT2-MV8 8 port SATA PCI-X card with R5.5. It seems that the module I need, sata_mv, is not compiled in the kernel or as a module. Line 1324 (if memory serves) of the /boot/config<TAB> says it is not included as module or in kernel. Anyone who may have a card based on Marvell Hercules-2 chipset beware. This particular card uses the Marvell 88SX6081.

Code:
# lspci -vv

I spoke to Cecil (cesman) about it and it was not included because it was marked "highly experimental" in the kernel. So, in order to use a card that needs sata_mv, here's what you need to do (all as root):

DO THIS AT YOUR OWN RISK! BACKUP/CLONE YOUR SYSTEM FIRST!

Get the kernel source from knoppmyth.net
Code:
dpkg -i linux-source-2.6.23-chw-4_2.6.23-chw-4-10.00.Custom_all.deb
cd /usr/src && tar jxf linux-source-2.6.23-chw-4.tar.bz2
cd linux-source-2.6.23-chw-4
cp /boot/config-2.6.23-chw4 .config
make menuconfig

Arrow down to Device Drivers > SATA (prod) and Parallel ATA (experimental) Drivers
In there somewhere is the Marvell driver marked highly experimental.
Highlight it and press 'y' It should have a * in the box now.
Exit out and when promted to save the configuration, say yes.
Code:
make -j2

Note the number following the -j should be the number of processers in the box x2. So if you have a quad-core, enter -j8, dual-core -j4 and so on.
After it finishes (it could take a while)
Code:
make install
make modules_install
lilo -v
reboot


Note that there were at least a couple ethernet device drivers (may be others for other devices, but I'm not sure) that were compiled from outside the kernel source tree. I believe they were the e1000 (for intel NICs) and a Realtek driver (not sure of the name). If you need these drivers, be sure to copy the .ko files to a safe place before running make install and then place them back in the proper directories after you run make install.[/b]

@mihanson - I followed your steps but it resulted in a kernel panic upon reboot. Please have a look at my thread here if you can help :)

graysky: not sure what it could be. My instuctions "worked for me" on the sata_mv module. Maybe your changes don't play nice with some other things in the kernel?

thanks for the reply.. I dunno since this is my first experience working with recompiling the kernels :) I think my problem is that I'm not doing something after the make install step... did you have to edit your /etc/lilo.conf or anything prior to the reboot command?

Code:
# lilo -v


But I thought you covered that here:
Quote:
Code:
# make -j2
# make install
 (answered yes to re-running lilo)
# reboot

Right, but since it wasn't mentioned in your steps, I just wanted to make sure. I just did a fresh install of R5.5, and didn't change any options, just copied over the .config and rebuilt the kernel which worked without a kernel panic. To me, that proves that the problem must be with something I'm compiling into it... I'm going to go though and just do all kernel modules now and see if it'll boot. There was one area (CONFIG_NF_CONNTRACK_MARK=y) that didn't offer an option for a module, either enabled or disabled. I plan to omit that altogether and see.

Thanks again for the reply.

EDIT: nope, kernel panic results from just adding module support :(

What is the correct method to save my out-of-the-box kernel as a third option in lilo's boot menu so that I can boot into it without having to do a new install from scratch?

Yeah, I forgot that step in my instructions, but I went back and edited to add that step.

I'm not versed enough in kernel compiles, but I'd think you'd need to give your new kernel a unique name and not use cesman's "default" naming convention.

Yeah, I had a look at /etc/lilo.conf and more or less just copied the default section. I copied the kernel and .gz to working and working.gz and edited my conf accordingly... I should now have three options. We'll see.

Figured it out... I was missing the #make modules_install step. Anyway, I wrote up an unofficial HOWTO: Install Moblock on R5.5 in case anyone cares to do so.

Post subject:  Thank you!
mihanson,

Just wanted to stop by and say thanks. Those steps worked perfectly. I installed R5.5 to my IDE boot disk, and then before running any of the setup scripts <CTRL><ALT><F1> to the console, and installed the custom kernel. When I rebooted it starts back up asking for the root password to run the setup scripts.

Now to LVM or to storage group... oh off topic.

Thanks again mabye R6 will have native support for Marvell :)
