Description
TLB multihit recoverable error.
External machine check interrupt.
Local back-invalidate snoop rejected. Should be set to recoverable.
This bit is set to 0 at reset and must not be set to 1. When read, this bit
can be 1 or 0.
A machine check interrupt occurred while machine checks were not
enabled. This error should be reported as a checkstop.
Note: Activation of an external machine check interrupt when
machine checks are disabled does not set this bit. The core does not
respond to the interrupt input when not enabled.
I-cache directory multihit recoverable error.
D-cache directory multihit recoverable error.
