My recommendation would be not to use ext4 or to convert to
btrfs unless
No way motherfucker.
On the old laptop I still use ext3, haha.
Will move this to upgrade warnings, just in case.

^ Absolutely reasonable to go ext3, but sure not butter.

I suppose this is applicable to everyone ( as in any distro ) running kernel 4.0.2-1 ?
Time to boot into 3.14 for me :(

It is not connected but I moved back to Debian kernel 3.16 because 4.0 sucks on my laptop. After booting from suspend it kills my CPUs.

^ The 4.0-kernel is way more CPU intensive for me here on this old T43. I can partly not even watch a video on youtube with 144p without stuttering and lockups. So, thanks for reporting, I wasn't sure if it's me or the box :)

4.0 is purely optimized for newer machines, from what I have heard. No one expected it to completely neglect the slightly older machines :/
But oddly, and please prove it guys, in Arch I have less issues, and I don't know why o.O Maybe the issue is more complicated. I am still a rookie in your presence :)
cheers

PS: It could still be a new bug, 4.x is still too new. Patience ;)

I am running Linux 4.0.4-towo.1-siduction-686-pae with no issues on my Dell Inspiron 1525, but I don't suspend nor hibernate so who knows. :)

^ Same here Gekko, no suspend etc :) Is that maybe a long running issue or? It should soon stop, because it is an old Linux diehard issue.

It seemed to work without issues but I need suspend. :)

Renamed the topic slightly. I am too lazy to open a new thread. ;)

Anyone care to test out the antiX4 kernels? let me know how they work on your box. Thanks.

^ Grabbing the 4.0.0-antix.1-486-smp now and will give it a hard ride over night! Thanks anti, I use your kernels quite often (to be honest, I am quite a bitch when it comes to kernels, so I change them /quite/ frequently), and the antiX kernels never disappoint.
Edit: first impressions are great so far. No more stuttering, the CPU doesn't go crazy (19% with youtube and this tab here open in Chrome). Great!

The ext4 bug is fixed. Let's see if the newer kernel behaves in other areas.

Jeez
I downloaded the bbq 64 bit Bork with 4.0.1.
Is there more to it then apt-get install new 4.0.3 kernel? Or an apt-get upgrade? Never installed a new kernel before.

The package called 'linux-image-amd64' will take care of the automatic upgrade to the next vanilla kernel in Debian's upgrade path. It's a metapackage that is linked to the newest kernel. Nothing else to do than a simple 'upg' in the terminal.

To do things the manual way, use this to see what kernels are available:
Then use "sudo apt-get install" to install whatever you want. This should automatically run "update-grub" and you're done.
Or stick with the metapackage bacon recommends if you always want to be using the latest kernel.
Or I think some guy maybe wrote a
kernel-install script that a few people have found useful. It might even be in Bork already.

^ That script is my favorite choice.
