Kernel 2.6.28 Notes and Upgrade to Ext4
Normally you don’t update the kernel at every release unless hardware doesn’t work as expected or you really need the slight performance enhancements you may get from new kernel technologies. But… if you have a new module you need to add you may as-well.
A great site that posts about kernel upgrades is kernel newbies, you’ll need to understand the options for updating and while you’re at it you can upgrade to ext4 – don’t worry, it’s easy.
Dog the Kernel
So you don’t download upteen kernel source between kernel update you may as well just unmask the version you need:
/usr/src/linux link to your the new kernel sources:
Here’s a few options answers:
If you want to find out if you BIOS is corrupted or if someone has been tampering with it:
2.6.28 can also Reserve low 64k of ram on AMI/Phoenix BIOS’s that as some developer that I lost a link to said, “This might as well solve a wide range of suspend/resume breakages under Linux.”
People may have heard about the new GEM Memory Manager for GPU memory that can help improve draw-speeds dramtically. GEM is a modern GPU memory manager and is already built into the kernel so it doesn’t need configuring. Only the intel 915 driver has this support yet but others will eventually follow.
Now build and install the kernel:
/boot/grub/grub.conf to add the new kernel:
Rebuild the driver packages that attach to the kernel (tell me if has to be done after reinstalling, cause I forgot to do it :) ):
Upgrading to Ext4
Ext4 is the evolution of ext3 and provides tons of enhancements. Ext4 looks to be a real good modern filesystem. Linux is good.
/etc/fstab and change filesystems from ext3 to ext4.
If you have a seperate boot partition, it’s best to leave it as ext2 or ext3. If
/boot is part of your root filesystem, you’ll need to install a patched version of grub that understands ext4. In Gentoo versions of grub greater than 0.97-r9 have the patch built-in.
Or whatever you hard-disk is.
Next you’ll need to boot from an installCD as converting partitions should not be done on mounted media. I used the Sabayon DVD. This step take like a nanosecond.
And you’ll need to fsck to fix the nodes.
All is good in the world. Adio!
