Kernel update and Highmem kernel
« on: February 08, 2010, 18:01:24 »


Updated version 2.6.28-dl-11 now supports more webcams (in the "media" package).
Also, we finally have a Highmem version 2.6.28-highmem-dl-11, which supports up to 4GB of RAM. It's the only difference between the regular and the Highmem version.

If you have 1GB or less RAM, stick to the regular kernel. It will perform better. Only use the highmem kernel if you have more than 1GB of RAM.

It's good to see DL evolving, it's just that others progress
was a slight misfortune to me.
After updating to kernel -11, DL got stuck at the command line
when booting. I guess this was due to the nVidia driver I had installed
in kernel -10, so kernel & xorg.conf did no longer match.
I managed to boot to Desktop after modifying xorg.conf to use the nv driver.
To reinstall the nVidia driver, I need kernel sources / pre-compiled sources.
Will you make them available?
I already de-installed the -10 kernel ... in a rush.
Any other advice?

R3,

A highmem kernel?!  Did you finally get a computer with more than 1 GB RAM for testing your creations?   Tongue   

Thanks for new kernel!

I don't need more then 1GB to test a Highmem kernel. Because a Lowmem kernel only supports 896 MB, while the Highmem one would enable the whole 1024 MB. However, the performance loss caused by the Highmem kernel is greater than the loss of 128 MB with the Lowmem kernel.

Nonetheless, I'll have you know, I own a 2 GB PC for a couple of years now. I'm not that quaint...!

Just teasing about a computer with the memory to benefit from with highmem support....    Cheesy  

I did encounter an issue with loading the firmware for the IPW2200 - I can see the kernel information in /usr/src/debris-2.6.28-highmem-dl-11/include/config for the IPW2200, but it does not seem to find the firmware - it does without issue with the standard kernel (so I know it is installed).   Huh

So I started digging...  Roll Eyes   It appears the /lib/firmware/2.6.28-highmem-dl-11/ is empty - unlike the /lib/firmware/2.6.28-dl-11 which has the firmware.  

I used:
 
Code:
sudo cp -r /lib/firmware/2.6.28-dl-11/* /lib/firmware/2.6.28-highmem-dl-11/

That did seem to work - I am connected via wireless now and it did boot past "Loading Hardware Drivers" without any errors this time.   Grin

I don't know if that was the "proper" fix though for long term use....

New firmware package available. Just update and the symlinks should be set.
