grub2 upgrade - problems

[klaus2008]

I would suggest the following. I suppose that you use your HDD install of Knoppix.
Boot the Linux 3.0.4 kernel. Open a terminal and issue

sudo lsmod > /home/knoppix/lsmodules-3.0.4.txt

Reboot the system, but now use the Linux 3.0.4-64 kernel. Open a terminal and issue

sudo lsmod > /home/knoppix/lsmodules-3.0.4-64.txt

Then you can compare the two text files and try to find out whether one kernel module was missing when you used the 3.0.4-64 kernel.

Thanks Klaus,

These modules are loaded by 3.0.4 but not by 3.0.4-64:

Module                  Size  Used by
arc4                     994  2 
lib80211_crypt_tkip     6273  0 
joydev                  6662  0 
wl                   1936903  0

and this module by 3.0.4-64 only:

Module                  Size  Used by
edac_core              30522  0

Reading around, I've found a post which advises

To make the module load at boot, add wl (and lib80211/lib80211_crypt_tkip, if needed) to your MODULES array in /etc/rc.conf

however on my system I don't have a /etc/rc.conf file. Should I create it, or do the module load instructions go elsewhere?
