Panic Report initproc exited exit reason namespace 2 subcode 0xa description none [duplicate]

Solution 1:

Your drive is failing.

The key to this diagnosis is this error message in the panic report:

> Root disk errors: "Could not recover SATA HDD after 5 attempts.
> Terminating."

To fully diagnose this, install macOS to an external drive. If your MBA starts to function normally, you've narrowed it down to your drive. (It can be a USB flash disk - it's only for testing purposes).

Luckily (as "lucky" as one can get in this scenario) the drive isn't soldered to the logic board so you do have the opportunity to replace it with another (128GB: PN# 656-0021A or 256GB PN# 661-02396). It's not too difficult a fix, you just have to remove the back cover and disconnect the SSD. ifixit.com has a good walk through.

Now, you DO have a backup, right?

If not, the good news is you can buy a sled or cable and attempt data transfer after you put a new drive in. Since reading data often works after writes to a failing drive are not happening. Sooner you power off and start data transfer the better.
