To the OP, try doing a google search on "cause = -122" (include the quotes).

Hello,

OK, I did a Google search on "cause = -122".

I found many entries, going back for years.

Sometimes the problem occurred at boot up.
Sometimes the problem occurred while the computer was running.

Sometimes software was suspected.

Sometimes hardware was suspected: The battery, the power supply,
the logic board, the drives, the cables, video cards, other cards,
a UPS, a surge protector.

Some people uninstalled software.
Some people uninstalled software, then reinstalled it.

Some people changed one, or more, pieces of hardware.

Some people changed both software and hardware.

Sometimes the problem went away after things were changed.
Sometimes the problem did not go away after things were changed.
Sometimes the problem went away for a while after things were
changed, then reoccurred again.

Conclusion: "cause = -122" is a general, non-specific, error message.

Comments anyone?

Bruce
