MacBook Pro Late 2009 SATA slow/resets. Is my motherboard dying?

  • 772

My MacBook Pro runs slower the longer it's on. I am getting kernel warnings.

Some, but not all, resets correlate with AC power connects and disconnects. I don't think the warnings do. (How do I tell?)

What are these errors? What causes them?

Can this damage the drive or corrupt data? What is it seeing that motivates these?

  1. This look like it might be the cause: https://bugs.launchpad.net/linux/+bug/576601

    I see you have not installed the Apple EFI firmware update 1.7 that is known to cause bus errors that can corrupt data due to faulty SATA2 3Gps support that the update turns on. That rules that out. Or perhaps your chipset is even worse than the average?

    Does anyone have a log of what the kernel errors look like for either the nvidia interrupt handling (supposedly fixed for a MBP7,1, though perhaps not yours) or faulty SATA bugs?
