From 615661f3948a066fd22a36fe8ea0c528b75ee373 Mon Sep 17 00:00:00 2001 From: Marcin Slusarz Date: Sun, 22 Aug 2010 20:54:08 +0200 Subject: [PATCH] drm/nv50: initialize ramht_refs list for faked 0 channel We need it for PFIFO_INTR_CACHE_ERROR interrupt handling, because nouveau_fifo_swmthd looks for matching gpuobj in ramht_refs list. It fixes kernel panic in nouveau_gpuobj_ref_find.
