null_audio: "page fault, but interrupts were disabled" after ~5 minutes of system idle.

Test System: Haiku hrev36939 with null_audio driver included in image and with removed hda driver. The Media server must be configured to use Virtual Audio for inputs and outputs.
The Problem: Wait after the system boot about 5-10 minutes. The system falls to KDL in null_audio/media_addons. The screenshot is attached.
Note: The same behaviour is observed with the draft version of my sis7018 audio driver: http://dev.haiku-os.org/browser/haiku/branches/developer/siarzhuk/sis7018. But the backtrace points to ExchangeBuffers call at line 203 of Stream.cpp. I can attach this screenshot too, if you need it.
I suspect that there is something wrong with implementation of null_audio and sis7018 because HDA driver on the same system do not force me to such problems.
