When Firewire-0 is present there's a memory corruction supposedly caused by the driver. This is the master ticket.

Does the crash happened just after an upgrade? Or is it persistent?

Did a fresh install of hrev49833 x86_gcc2 on my second test PC pkgman full-sync to 49852 x86_gcc2 reboot media_add-on server debug report appeared on desktop after the reboot Was this automatically generated? I did not see any debugger dialog, nor did I input a command. debug report attached

I think the common factor between all bug reports that I've seen is that the FireWire-0 control is there. This might be cause of some buffers mismatch or area offsets overflow since those threads live in the same team (the media_addon_server).

A test that might be useful is if you disable firewire from bios or blacklist the right drivers so that we can see if the problem is still happening.

I'm not so sure this issue is persistent enough to easily track down. I saw it happen only twice during a week in which I was at home on a work break, doing a lot of testing for Haiku. Prior to the first report, I had not seen a media_addon_server crash for quite some length of time. Of course, I'm always willing to assist however I can, to help Haiku progress toward a stable Beta release. I'll try your suggestion should the problem become reproducible.

I fixed different occurrences of this bug, only one of them was replicable on my system and it happened at very high load of the system (such as 20 videos played at the same time). I don't see this bug on my pc since then, and also I don't have a firewire. So if we could confirm that disabling it the bug doesn't occur, it will be helpful to finally fix the source.

Did a fresh install of hrev 49857 x86_gcc2 on my PC...

pkgman full-sync


media_add-on server wont crash anymore... Maybe fixed?! Strange...
