RE: SS4000E Kernel v3.4 Config



For my experiments with building a new 2.5.32.5 kernel for the ss4000e I've
been using the initrd.gz from the latest ss4000e build at
http://d-i.debian.org/daily-images/armel/. I now think that initrd needs to
be rebuilt specifically for each kernel version. After getting to the point
in d-I where the 'no kernel modules found' error occurs, I go back and open
a d-I shell and see that the modules are at /lib/modules/2.6.32-5-iop32x/...
and this same path is of course in the initrd when I extract the initrd
files to a temporary directory with cpio. The version number of the kernel I
built (shell uname -a) is 2.6.32.5 so it's not surprising that d-I fails to
load any modules. Even adding -iop32x to the kernel version string in
menuconfig can't fix this (-5 not .5).

Does this seem like a correct conclusion that initrd must be rebuilt for
each kernel version?

This would also explain why the n/w card wasn't found if the e1000 driver is
set as a module but was found if set as built-in.

I guess there must be a build script for initrd.gz and zImage that are at
http://d-i.debian.org/daily-images/armel/daily/iop32x/netboot/ss4000e/ which
I could use? But I failed to find it.

At the download installer components step, d-i halts with the error 'no
kernel modules found' which I think is fatal.
The same symptoms/error occurs for both 2.6.32.5 and 3.4 sources from
ftp.kernel.org.

I'm not sure where to go next? Any suggestions are hoped for.

Set n/w card e1000 driver to built-in
Patched zImage with the machine number patch (per Arnaud)  $ ( devio 'wl
0xe3a01c04,4' 'wl 0xe38110bc,4'; cat zImage ) > zImage.ss4000e and then used
zImage.ss4000e
     ## prepends 8 bytes machine code to set right machine number
zImage.ss4000e size is then 1492880 (for 3.4)

n/w card is detected
DHCP succeeds
No kernel modules error

I had tried that before but to be sure tried again.

Setting the e1000 driver to built-in instead of module and rebuild. 1.5M
still.

N/w card is detected this time but DHCP ip acquisition fails, so that's a
step forward I guess. I know DHCP is available from the n/w because 2.6.32
worked OK and other machines get it.

Continued to configure n/w manually with an IP, GW, DNS etc. This fails to
retrieve files from the Deb archive mirror, so the n/w is apparently not
functioning really.

the network driver is in module so you need to find a way to load it while
installing with d-i. Given that the zImage size is 1.5MB, maybe you can try
putting the ethernet driver built-in instead of module to workaround that ?
