3.2.9. 1930283: The PE might deadlock if Pseudofault Injection is enabled in Debug State

Description

If Pseudofault Injection is enabled for the PE node (ERR0PFGCTL.CDNEN=0x1) and the PE subsequently enters Debug State, then the PE might deadlock. Alternatively, if the PE is executing in Debug State and the PE enables Pseudofault Injection for the PE node (ERR0PFGCTL.CDNEN=0x1), then the PE might deadlock.

Conditions

  1. ERR0PFGCTL.CDNEN is set to 0x1 to enable Pseudofault Injection.
  2. The PE enters Debug State.

OR

  1. The PE is executing in Debug State.
  2. ERR0PFGCTL.CDNEN is set to 0x1 to enable Pseudofault Injection.

Impact

If the above conditions are met, then the PE might deadlock.

Workaround

Ensure ERR0PFGCTL.CDNEN=0x0 before entering Debug State and while executing in Debug State.
