Bug Description

I have installed both the i386 and the amd64 versions of Ubuntu Studio 9.04. After installing and loggin in, the cursor moves extremely slow, and then, locks up (freezes). Sometimes once I start Update Manager. Other times, before I can even click on Update Manager.

I have WinXP and Ubuntu 9.04 (both i386 and amd64 - separate partitions) running on this pc already (and was using Ultimate 8.10 before, i386 and amd64 versions on separate partitions).

My pc is comprised of the following components to help you review this report:

EVGA i780 Motherboard (775 socket)
Intel E8400 3.0 Ghz CPU
8 Gb DDR2 800 RAM
XFXForce 8600GT 1GB DDR2 RAM Video Graphics Adapter Card
Maxtor 500Gb SATA-II Hard Disc Drive
Asus DVD Drive
Seasonic 600 Watt PS

Hello,

I think i have a similar bug.
Ubuntu Studio 9.04 AMD 64 freeze when i run Update Manager or when i get content from internet with apt-get upgrade.

Fisrt, the migration from 8.10 has failed, in the end of installation before cleaning the system it deletes everything on my desktop (but not the wallpaper) and freeze.
After rebooting, a dpkg --configure -a freeze when getting content from the Internet (in console mode, in graphical mode screen was empty).

So i decided to reinstall 9.04.
Everything went ok, reboot, set my /home partition, got my desktop as in 8.10 BUT icons didn't display their names but "xxx.desktop" with a default icon, and double clicking on them display a message box with "Launcher marked as not safe". Even if i marked them safe or create a new one, they are not displayed as they must be and they're always marked as "Not safe".

But the most important bug is when i get content from internet updating my packages.
Screen and mouse freeze. It seems to be the internet connection manager which is bugging.

Config:
AMD 64 4200+
Asus A8N32 SLI Deluxe, 2 GB RAM
Triple Boot Vista, Ubuntu Jaunty, Ubuntu Studio with /boot on a specified partition
Internet connection: wired on NVidia CK804 or Marvell (tested with the two, bugging)

I experience the same problem!
When I try to update my Ubuntu Studio 9.04 it freezes and I can't do nothing!
FIX THIS BUG! OR POST SOME SOLUTION!

I can confirm this behaviour on my system as well.

When running update-manager or synaptic, the system freezes/kernel panics.
I can run apt-get -upgrade from a virtual terminal.

Hello,

same on my machine:

CPU: AMD Athlon X2 3800+
Mainboard: ASUS M2N-SLI
Graphics: NVIDIA 7600GT
Memory: 4GB DDR2
Filesystem: ext4
Using real-time kernel

I installed the new version of Ubuntu Studio (9.04 for amd64) yesterday evening.
During installation everything went well but after reboot the system didn't come up.
After several resets the system came up but it frooze short after login.

Can't tell what the cause is but probably there is a problem with the real-time kernel
in Ubuntu Studio.

ubuntu studio 9.04 freeze after a while, often when accessing net (synaptic or firefox) with progressive feeling : wacom tablet stops then the other ps2 mouse ; the display remains the same but nothing works...reboot...

"Normal" jaunty works normally

I've tried both 32 and 64 bit amd install and experienced the same prob....

PLEASE, DO SOMETHING ! I have work to do !

cordialement,

I think this may be related/duplicate to bug #354816 and #364530, maybe others.

In that bugs the system seems to freeze at some point with the -rt flavour of the kernel and some network stuff going on, and the problem dissapeared if the kernel was booted with nosmp or disabling network interfaces.

Yes, you're right, but it's really a pity to specify "nosmp"because I
get only half of the processor power !
But it works, Thank a lot !

Hope that it will be corrected soon...

Still the same issue in UbuntuStudio 9.10 with kernel-rt on amd64 x2. Works OK with "nosmp" option.

Any clue when a solution may be available?

The only way i found is to compile the latest kernel patched with rt.
I made this since "nosmp" make my Ubuntu works, but with only one processor.

Actually I have 2.6.31.4-rt on UbuntuStudio 64 bits and everything works fine !

For me its fixed in 9.10, at least with this kernel:

Linux hydra 2.6.31-9-rt #152-Ubuntu SMP PREEMPT RT Thu Oct 15 13:22:24 UTC 2009 x86_64 GNU/Linux

It has been running about 4 or 5 hours downloading stuff without issues.

In the previous bug reports (this and others that seems to be duplicates of this) the bug aparently happened on any multi-procesor machine, but now it seems to happen only on AMD, or we are talking about different bugs. I'm on a Intel Core 2 Q6600.

Also note, the new -rt kernel seems to work very well for me :D.

Yes, I am very surprised that such a bug have never been corrected since
this time, because it's a very big bug : the system just don't work !!!

Anyway, it's a bad news, I was hoping the 9.10 ubuntustudio working fine....

I just want to confirm that I am having the same issue. I just added all the Studio packages to my vanilla 9.10 install and downloaded the rt kernel. Generic kernel has no problems, but the rt only works with nosmp.

Oops, I should add to the above post that I am using the 64-bit edition. I tried 64 Studio a while back and had no similar problems.

I am having the same problem. I originally was using "nosmp acpi=off" but have determined that only "nosmp" is required. Regular kernels work fine just not the RT realtime version.

I am running Studio 9.10 i386 version. My processor is Intel P4 3.2ghz Prescott, 2.5gb RAM, MSI PT880 system board.

So far everthing works great except SMP. Very nice distribution!

Bonjour,

"Very nice distribution!"....hum....this is an old bug, a very old one,
present already in the past version, that prevent running ubuntustudio
for an lambda user : it's not very nice.
Without smp you're losting half of your computer power, not very nice too.

It is some ubuntu kernel patch that causes that, because with a
self-compiled vanilla kernel with rt patch everything works fine, BUT
you cannot access to ubuntu restricted driver for a nvidia video card,
you must install from nvidia directly (I've never tried...)

But this is the solution that I prefer : I need full power of smp.

Hope that old bug will be corrected, but I don't believe that is close
to us.
