Kernel update
« on: March 09, 2011, 07:30:41 PM »
I just read Tex' kernel update post.  2.6.37.2 is available.
Is this the one optimized to work with my Intel i3 core processor?

If so, I'm guessing it might be this one I need?

Quote
i686 linux kernel with the BFS scheduler
This kernel package contains the Linux 2.6.37.2-pclos1.bfs kernel patched with the BFS scheduler from Con
Kolivas. It is optimised for i686 CPUs, supports up to 4GB of system memory (highmem enabled). The
kernel timer interrupt is set to 1000 HZ, it defaults to using the 'BFS' scheduler, 'SMP' is enabled
and is compiled with kernel preemption enabled.

Or do I need to wait for another component?

Or maybe this isn't it at all?
Toonfully,

Heya Mark.

For us newbies (and that includes me too), here's what I would do. I would install the kernel but would keep the previous on that works for me. After installing the new kernel, I would check /boot/ and make sure the symlinks (is that what it's called?) for initrd.img, vmlinuz and config point to the same kernel versions. Meaning if vmlinuz points to the 2.6.37.2, check that initrd.img and config does too.

Then check /boot/grub/menu.lst to make sure that all those vmlinuz, initrd.img and config are on the same block starting with title and ending at img. Also double check that your previous kernel is intact in case the new kernel doesn't work on your machine, you can reboot back to the on that works.

The new kernel might take a while to install the modules needed to run your pieces (of hardware and driver) so be patient. Better if you can press Esc to go verbose mode so you can see what is happening underneath all those blues and greens. But if after TWO hours, nothing (and I mean nothing) improves, try it one more time with a hard boot. Note where the bootup had stalled and if on the second (or third attempt), hopeless is the only word you can think of in your mind, go reboot back into your previous kernel and post your report.

I hope I made sense in this post. I think I might have to look for Neal so I'd have someone to drink coffee with.  :)

Good morning from China.

Archie,

Thanks.:) I just checked synaptic and not all packags could be retriv.so, looks like somethingis snycing up.
How do I nmake sure I kepthe current kernel? simply make sure nto to unistal it,correct? it shouldremian even when i do a kernel update, I'mpretty sue.
I think I do need an xorg update for this as well.
Toonfully,

The previous kernel should be OK even if you install a new one unless modules are also updated then the previous kernel still need to build the modules.

And you should know by now how important backup is. Best solution of all is to remaster an install you can be proud of so all you needed to backup (regularly) is your /~. Still, I think the previous post limits the risk of any unexpected "bork" ;)

Installing one kernel does not remove the other kernel. You have an option to boot into the default kernel or the new kernel. This gives you a chance to run the new kernel for a while to make sure it performs properly on your hardware. If not you can always boot the original kernel.

Yes you need new xorg and Intel Video drivers before you can take full advantage of the i3core.

Okay then.  I'll just sit quietly over here in the corner and wait for the other stuff.:)  (As if THAT'S possible. ;D ;D)

Buuuuutttt...if I install the new kernel, what difference am I going to see?  I mean, why a new kernel?  Better Hardware support?

It gives you the right to proclaim yourself "A REAL MAN" ... "I run the latest and greatest Linux kernel" ... (don't know why, but it sure sounds manly and geeky, at the same time;D ;D ;D

Well, then, I might give it a go.:)  Google Earth won't run (even the non GL version).  And this is due to this Intel Core i3 chip.  As Tex pointed out, I'll ned the  "new xorg and Intel Video drivers before you can take full advantage of the i3core."  So, I'm just debating if I should grab this kernel now, or simply wait for everything else. I'm not sure the kernel alone is going to do much.

I don't think that two words can go in the same phrase  ::)
I shall pass this way but once;
any good therefore that I can do,
or any kindness that I can show
let me not defer nor neglect it,
for I shall not pass this way again.

Most definitely extra hardware support .......  for instance two devices I have here had no support in kernels previous to 2.6.37 are both now working with this kernel.

I can now watch DTT on my TV from a USB dongle and can broadcast it on the LAN.
I can use the Video Grabber dongle to take in analogue video and digitise it.

So this was a huge step forward for me.

There are lots of other things also, but if you do not have anything which is not working presently, then there is no pressing need to upgrade the kernel.
On the other hand, the newer kernels are generally a bit faster so there might be a speed gain to be had from the newer ones.

regards.

I can't wait for 2.6.42.1 and boot to the desktop in under 10 seconds :) :D :D

Yeah, yeah ... I wish ;)

You can have it now! Get a SSD hard drive and PCLinuxOS will go from Grub to KDE desktop (with autologin) in about 10 seconds.

The new kernel could be good for a new Intel MoBo I got, there are some things not supported right now

In that case, I'll give it another year to get a new PCLinuxOS system.  By that time, the capacity of an SSD will go up and the price should fall.:)
