<p>Howdy,<br></p>
<p>Diffed the configs for 3.4.2-3 and 3.5.2-3.</p>
<p>The 3.4 kernel had these kernel config's:</p>
<p>CONFIG_PANEL_DVI=m<br>
CONFIG_SND_OMAP_SOC_HDMI=y<br>
CONFIG_SND_OMAP_SOC_OMAP4_HDMI=y<br></p>
<p>Could that contribute to the lack of HDMI/DVI-D on pandaboard on the more recent kernels?<br>
Possibly in addition to the omapdrm module not loading during boot?<br></p>
<p>Thanks<br>
