<pre>So, i tasted with latest git 3.10.0-rc7-00854-gf19c9d3 - same result.
(gdb) l *intel_crtc_set_config+0x216
0x2bab0 is in intel_crtc_set_config
(/home/lex/tmp/linux/drivers/gpu/drm/i915/intel_display.c:8678).
8673 int num_connectors)
8674 {
8675 int i;
8676
8677 for (i = 0; i < num_connectors; i++)
8678 if (connectors[i].encoder &&
8679 connectors[i].encoder->crtc == crtc &&
8680 connectors[i].dpms != DRM_MODE_DPMS_ON)
8681 return true;
8682
I noticed that in some circumstances i null pointer dereference on xhci driver.
Interesting, are these errors connected? Or may be there is some memory region
used by what ever, bios, efi?</pre>
