'nuff said.

[mastermindg]

I saw it come in. Good times.

[hardyn]

where can one find release notes? to know exactly what was adressed in this new kernel.

[FuturePilot]

Suspend is still broken
https://bugs.launchpad.net/bugs/226279
:(

We're working on it though. :)

In Synaptic highlight the package and then go Package→Download Changelog.

[Sef]

I updated to it and found my computer boots much faster now.

[stchman]

What did the new kernel fix?

[FuturePilot]

From the changelog

linux (2.6.24-18.32) hardy-security; urgency=low

[Upstream Kernel Changes]

* CVE-2007-6694: [POWERPC] CHRP: Fix possible NULL pointer dereference
* fix SMP ordering hole in fcntl_setlk() (CVE-2008-1669)
* Fix dnotify/close race (CVE-2008-1375)
* tehuti: check register size (CVE-2008-1675)
* tehuti: move ioctl perm check closer to function start (CVE-2008-1675)

[quanumphaze]

Suspend seems to work fine for me.

Sound had stopped working through the headphone jack though that could be a BIOS problem that has been with this laptop from day one (problem with Windows too). Which coincidentally is fixed by using suspend.

Seriously though, what does this all mean? Alls I knows is that glxgears gets higher FPS than it used to, and I can't decipher anything out of the changelog. :(

I don't know what the significance of this is, but it looks good :)

[jw5801]

The kernel appears to be quite nice, although it's package didn't install linux-ubuntu-modules-2.6.24-18-generic as a dependency. So I had no ndiswrapper module (and thus no internet) on a reboot which was mildly annoying!

[bash]

Hmm this question is kind of offtopic. But maybe someone knows:

Did they fix the random kernel crashes that occured when Hardy came out. It was marked as a high priority bug but was triaged.

I had the problem on one of the machines and just compiled the 2.6.25 Kernel. So I never followed up if with the new kernel updates for .24 the problem was solved.

Does anyone know?

[prshah]

[UbuGr]

Hello,
I just upgrade to 2.6.24-18-generic.In the boot loader(grub) i see the options to start with this and also with older kernels.

My question is what happens after a kernel upgrade, now i have three stand alone kernels in my system? 2.6.24-16 , 17 , 18 ? or one kernel is a upgrade of other.

What should i do,remove older kernels ? or keep them all and change menu.lst file to don't show me 6 records on booting.

thank you.

If you type sudo apt-get autoremove into a terminal, one of the older kernels will get dropped.

Open System -> Admin -> Synaptic and search for linux-image. Choose the old kernels that are no longer required and mark for complete removal. The change should also reflect in your GRUB.

[Swarms]

It ruined both my nVidia card and my Intel Wifi card *sob*.

Uninstalling, though I would have liked increased performance. :o

It may not have. Try installing:

sudo apt-get install linux-ubuntu-modules-2.6.24-18-generic
Assuming you use the generic kernel. If you use ndiswrapper you'll need that to get the module for it. Dunno about nvidia though.

[PrimoTurbo]

Umm, what video card do u have. Under my P4 1.6Ghz and a 9700 Pro 128Mb I get close to 5000 FPS. And you are happy with a little over 1000?

[xjgnsdof]

I updated to it and found my computer boots much faster now.

I see about 10 seconds shaved off of my boot time. Is that really because of the kernel?

Yeah that was the one I installed since it was similar to the one I use now (except the version ofc.) I don't use a wrapper for the driver, it used to work oob, and I won't try to fix something that already worked before.

Got no idea of the nVidia either. :)

Ah, well. Worth a shot. I honestly have no idea why linux-ubuntu-modules-2.6.24-18-generic didn't install as a dependency of linux-image-2.6.24-18-generic. They're both part of the base system! Well, the -16 versions are anyway.

[FuturePilot]

Make sure you have the latest linux-restricted-modules package installed. X broke on one of my computers after the last 2 kernel updates and I couldn't figure out why. I didn't install the Nvidia driver manually I used the one in the repos. I finally found out that somehow the linux-restricted-modules metapackage got uninstalled. Therefore the linux-restricted-modules package never got upgraded.

[sports fan Matt]

downloading it now...

I noticed it when I went to reboot after installing the new kernel.

Ok restricted modules solved the nVidia problem, gfx is working great, but sadly neither sound or wifi works, just like in Feisty and Gutsy. Have they removed support for what I thought modern hardware?

Edit: btw. I am using a Intel 4965AGN wifi card, and a Realtek HD audio card in the ICH8 family (I think).

I have the same wifi card, and it's working fine...

Thats strange, please explain what you did.

[spidermonkey]

I got the same problem with Intel PRO/Wireless 3945ABG/BG . It has problem since 2.6.24-16 upgrade. Earlier it used to show AP's but after this upgrade can't see a single network.

Its weird that its complains for kill switch. any clue?

[klange]

I'd say the only problem is that it thinks your kill switch is on. ;)

[spidermonkey]

The hardware switch seems to be fine. I got the LED light too . Is there anything I need to set as option somewhere? The wireless and bluetooth have the same switch and bluetooth seems to be alright.

[art.vandelay]

Installing this new kernel also borked my graphics card. It was booting into a "low graphics mode".

I found this topic and all the linux-restricted-modules and linux-ubuntu-modules were already selected so I just checked them all (including the kernel) for a reinstall in synaptic and everything's ok now. :)

[SomeGuyDude]

When I upgraded everything blewthehellup and I had to do a complete reinstall.

[Sunflower1970]

Updated both laptop and the Dell desktop. Everything seems fine...I don't notice anything different in speeds or glxgears...

[Nessa]

Just updated. Seems fine here too. I'm now hesitant to add ubuntu to my vaio running vista. It seems laptops get most of the problems during updates.

[sports fan Matt]

I didnt have to do a reinstall, but i did a error stating I passed an undefined mode"

[OpposingForce]

I just got the 18..it runs perfectly after it updated the modules.

Also excuse my noobiness, but according to this page

http://www.kernel.org/

the latest stable version is 2.6.25.4. How come the latest version on ubuntu is 2.6.24-18? It's just something I've been wondering about, if anyone can answer thanks

It's just something I've been wondering about, if anyone can answer thanksThe Ubuntu kernel is different from the plain ol' vanilla Linux kernel. The Ubuntu team makes various additions and subtractions to the kernel and does various tests before it makes it into Ubuntu. Because the Ubuntu team does these things to the kernel, Ubuntu is always a few kernel versions behind the current kernel.

At least, I think that's the case.

That, and an older kernel means more stability.

Why didn't you just boot back into the old kernel and continue using that?

Not so much that they do various changes to the kernel. More that going from 2.6.24 to 2.6.25 is a reasonably major leap and likely to change a few under-the-hood things (similar to an upgrade from Gutsy to Hardy).

A more established kernel generally means less bugs. Also means no support for the latest features and kernel modules however.

This is a triumph. I'm making a note here, huge success.

If you have a Nvidia card, don't bother. X won't start with the older kernels.
