Not detected. Tried all the other cards one at a time. None of them are detected.
What the heck is going on?!?!?!?!?! I swear, if it weren't for bad luck, I would have no luck at all. Any ideas guys? Does the UP7 need the pin mod for X1 devices to be seen? I am so confused.

And the error:
Some more facts that might help:
1. When I used to run only 2x270, it ran for days without issues, at 480kh ea
2. When I used only 3 or 4 cards in current setup, it still crashed with any 7950's in there
3. Tried all the way down to I=17 and still crashed
4. Tried raising and lowering mem & engine clocks up to 20% both ways, still crashed (but random settings)
5. Changes in ambient temps dont seem to matter, crashes seem random
If you need logs, I would like to see them too, where can I find out how to do that?
That link u sent me seems like a good band aid...
I went to File Manager, added kernel.panic=7 as the last line of /etc/sysctl.conf, and rebooted, did I do it right... A GPU fail will trigger the kernel panic and it reboots, done?
That "error" is actually normal as far as I've seen (the one on your image). It actually is a warning about low hashing, because you aren't actually mining. It has been suggested that mixing cards can cause instability, it should be doable but that could be a possible problem you are up against.
Do you have sufficient PSU for all the cards? Have you tried say, 2 x 7950's by themselves and see if they can mine fine?
One more thing to keep in mind about BAMT, is it can get corrupted. Certain flash drives just have a problem with installing and running the OS, so you might even try installing it to another flash drive, or reinstalling on the one you have. One of the ways I have noticed you cantell if it is failing, when BAMT is initializing at startup, it goes through a list of about 20 things that come up green if they are OK, and it says OK next to them, or if they failed it says something else (maybe failed) and turn up in red. I know on one of my miners the graphing utility has crashed on the OS and it won't work anymore, but it still mines just fine so I don't worry about reformatting it.

Ouch any more details how this happened?
I had to split two power supplies (650 and 400) to support two 290x in one board.
400 - supplying mobo and one 6-pin to one gpu
650 - two 8 pins and one 6 pin to two gpus so I had to use splitters.
Actually the other 8pin (pci-e) of the 650w turned into flakes. I had to use the molex to pci-e now but not sure if the 12v rail will hold - i guess we will see later tonight lol
Well no wonder it burnt up, you can't be using power from 2 psu into 1 card, bad bad bad.
