I've spent more time than I should have researching the PandaBoard.
Since the board is designed as developers system its got a few rough edges.
Use of full memory increases the chance of crashes.
Have they worked out if this is a Linux issue or a hardware fault?
There are several other causes for boot crashes and run time crashes (like network initialization on boot).
Hmm, firmware issues for boot crashes?
The DVI outputs aren't enabled unit (nor is the LCD output).
What, by default or is it physically not capable of doing so?
Sound files and HD video still may experience some stuttering.
Codec/driver/scheduling conflicts within the kernel. Given similar issues being noted with other similarly powerful hardware I'd be inclined to look at drivers being the culprit with HD video/sound issues.
I haven't checked on how open the PowerVR GPU is to development.
There is apparently a public SDK.
I haven't seen anyone use the expansion bus yet.
Still, it does look neat.
What does the expansion bus offer that isn't onboard?
