820-3115-B stuck on boot

[dukefawks]

Did you try with a known good stick of PC10600 RAM?

 

[SMMRepair]

Just an FYI, the 820-3115 uses PC12800 RAM as standard.

 

[WeLoveApple]

I tried with many kinds of good ram sticks. Still the same.

 

[WeLoveApple]

No Title

I tried. Same results.

Hope this one uploads in bigger resolution.

Upload somewhere else. That is a verbose boot screen. Does it always kernel panic when you boot normal?

 

[WeLoveApple]

Yes it does kernel panic every time with normal boot too.

I have no idea, could be anything that hangs the CPU. One thing to try is the BIOS, backup original!!

 

[WeLoveApple]

Re-flashed the bios. This time it will boot very very slowly and at the end of the boot just stops.

Need a clean ME to work, try this one:

Tried this one. Same results.

Run EFI version of ASD and check for errors

 

[WeLoveApple]

I did. No errors.

 

[dukefawks]

No idea, it could be anything. Any clues when you boot in verbose mode?

 

[WeLoveApple]

Some kind of CPU panic "TLB invalidation IPI timeout" , "CPU(s) failed to respond to interrupts"

 

[dukefawks]

Yeah, this can be anything. I doubt this is worth trying to fix unless there is some history as how this happened.
