KDL page fault re-starting tne media server.

From the Media Preferences app, select Restart Media Services and the system stops with a KDL page fault. I am using Auvia 8235 but the system always defaults to VIA VT82135 after updating to a newer HAIKU version. This device will not produce any sound. Setting the system to use the Auvia 8235 for input and output then restarting the media services will always KDL. after rebooting, the proper audio device is selected and the sound system then works.

Could you provide a stacktrace ? (type 'sc') Thanks.

As close as I can get to a stack trace. It's not a very good image I'm afraid.

Indeed, the photo is pretty bad - try without the flash next time, and try to put your elbows on the table as a tripod replacement :-) Anyway, it looks like it's somewhere in OSS.

Yes I know about it. I first need to port my changes to the mercurial tree before I can investigate. Btw, it might be due to the fact that 2 media nodes exist (one in /boot/beos/add-ons from jam and one in ~/config/add-ons from the optional package). It shouldn't KDL anyway but maybe if you remove one it will work around it meanwhile ?

It might also be due to conflicts with the native driver... but that can't be fixed before Haiku has proper device resource reservation.

Replying to mmu_man:

No... still end up in kdl.

here is a better image of the stack trace ( different camera .)

This bug seems to be squished. I can now restart the media server without the KDL issue. Please close the ticket.
