I have a fresh installation of Debian Jessie, with Cinnamon and Gnome. I run it on a decent computer with the following specs:

Athlon II x3, 6GB DDR2, 2GB SWAP (swapiness minimum), 600GB SATA HDD (new), Nvidia G210 with latest drivers ...

I have all latest updates and Ubuntu works well, however, Debian freezes for about 30-120 seconds when I start some applications. I am able to move my mouse, but not able to click anything.

I have tried rebooting and re-installing Debian but the issue still persists.

It would appear that sometimes the computer runs slowly, but only on Debian Jessie. I am able to run Windows with only a few problems such as a DPC latency issue. However, a reboot fixes the problem.

I forgot to mention that Debian Jessie is unable to hibernate. It hangs on a black screen indicating there is no video signal. Only issuing a hard-shutdown works.

I captured this in dmesg 15 minutes before the error:

[45967.243270] perf interrupt took too long (2517 > 2500), lowering kernel.perf_event_max_sample_rate to 50000
  • anything in dmesg (or journalctl -b0 -k) from around when its happening? – derobert Mar 30 '15 at 20:11
  • Just updated question with links to those logs. Thank you for your interest to help me out! Sublime took around 30 seconds to load one of logs... Too long... – xZero Mar 30 '15 at 20:21
  • I don't see anything in the kernel logs, unfortunately. Is it only the first time you start the app? Is it the same app(s)? Also, if its easy enough to reproduce, how about an iostat -kx 5 running (in a terminal) while you start one of those apps and it takes forever. (You might have to install the sysstat package.) – derobert Mar 30 '15 at 22:30
  • No, it's always, happening with Archive Manager (opening/closing), mplayer/mplayer2 (starting), Chrome (uploading, downloading, minimizing), NetBeans (starting/closing/creating project). All text viewers, especially default ones, and few others. iostat -kx 5 - imgx.elite7hackers.net/vKJ7se1IG3o3s/2015/03/30/… <- Captured while reproducing the issue – xZero Mar 30 '15 at 23:33
  • Forgot to mention that while running iostat -kx 5 freeze periods are a lot shorter. Weird. – xZero Mar 30 '15 at 23:45

I forgot that except Cinnamon, I also have installed KDE Plasma, and I decided to give it a try.

And guess what? For now, my system is faster than ever, it simply flys and there is no random freezes at all.
So obviously, problems is with Cinnamon and/or it's configuration and/or it's "cooperation" with Debian Jessie.

Thanks to derobert for all effort to help me out.
I appreciate that.

  • Debian Jessie freezing in Spain too, and this is plasma desktop installed in a brand new box. Three freezes in two days. – 41754 May 14 '15 at 19:40
  • It's not much better for me neither. It is not feezing that much, but it's kinda too slow comparing with another distros running KDE Plasma. – xZero May 16 '15 at 18:47
  • I'm attributing that to nvidia now. I hope applying https://wiki.debian.org/NvidiaGraphicsDrivers will work. – 41754 May 17 '15 at 15:57
  • linux-headers-amd64 is already the newest version. nvidia-kernel-dkms is already the newest version. They realy need to take care about their Linux drivers. It seems that's a place where bunny lies. – xZero May 18 '15 at 10:21
