My amarok suddenly crashes quite frequently, without any warnings or anything.
I am running Fedora Core 4, and I have tried many different versions of amarok, both from RPM\'s and compiled from source, but I always get the same silent crashes.
I am currently using the Xine engine, and it all works really fine, for about
half an hour tops. I have even tried with different soundcards, and I have also tried re-installing Fedora, but nothing seems to help.
My computer is a Pentium 4 2.4, 512mb RAM, Sound Blaster live! 24 bit soundcard, abit IS7 motherbord.
I have the latest Xine installed, I have updated everything on my system, and my current kernel is 2.6.12-1.1447_FC4smp.

Here is a backtrace from one of these crashes:
(sorry for the long message, but I don\'t know what is important and not in the backtrace...)

==== file `which amarokapp` =======
/usr/bin/amarokapp: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), not stripped

Does anybody have a clue what causes these crashes? Any helpfull tips would be greatly appriciated, because I would really like to be able to use amarok, it is just such a great program.

Disable HyperThreading. amaroK doesn\'t currently work with it.

Should I just boot with the UP kernel and re-installl amarok (just reallized I never even tried to do this :blush: ), or should I disable HT in bios completely? I\'m currently dualbooting Fedora Core 4 with Win XP, so I would rather not disable HT completely...

Disable entirely. Just reinstalling won\'t help at all.

So it doesn\'t matter if I use the smp or up kernel then, as long as I disable HT in bios, right?

Correct.

Well thanks a lot for the very fast help. I\'ll try it right away then. By the way, superb application and great support! Best media player ever!

markey, wouldn\'t using a single-processor kernel be good enough to disable HT?

There\'s also a rumor that the HT problem is only on preempt kernels. If your feeling bored you could test that.

Yeah, that would prolly do the trick too. You can hand some parameter to the kernel at boot time for disabling SMP. I forget which parameter it is, though. Google will tell.

Well, atleast it works if I disable HT in bios. I have had amarok play a dynamic playlist now for about 3-4 hours straight, with no problems. But fact of the matter is that Fedora Core installs both SMP and UP kernels, although I don\'t actually know precicelly what happens if I load the UP kernel with HT enabled. I will try that tomorrow, and test it to see if amarok is still stable in that enviroment... I can post back then, and tell the results. Again, thanks for all the help, I seriosly didn\'t expect that much help in that little time!

I just thought I should share some results from my testings today. It seems that the easiest and perhaps the best way to come around this problem is to add \'NOHT\' to the boot parameters for the kernel. This way, I do not have to disable HT in bios, so it is still enabled when I boot win xp. Amarok seems completely stable too, and furthermore, if I write \"cat /proc/cpuinfo\" it still lists 2 virtual cpu\'s. I don\'t exactly know what effects this have on the general performance, but atleast amarok seems to use less cpu this way, compared to when I disabled HT in bios.

Hmm, thanks for the heads up.

We should add this to the wiki

I suppose there are plans on getting amarok to work with HT. How far from achieving that are you? I kind of like amarok but will not disable my HT, which leaves me with other players while waiting for the HT support.

Well, we\'re investigating the issue, but we don\'t believe that the fault is actually in amaroK. We rather assume it\'s a kernel (scheduler) issue, or a problem in a library.

One of our devs has started talking to kernel hacker Con Kolivas, we\'ll see if he has some ideas.

I would be interested to know: Does the problem also occur with MySQL as database backend, or just with SQLite?
