11.2 SMI Timeout

SMI stands for system management interrupt and is an interrupt that gets generated so the processor can service server management events

(typically memory or PCI errors, or other forms of critical interrupts), in order to log them to the SEL. If this interrupt times out, the system is frozen.

11.2.1 SMI Timeout – Next Steps

This event normally only occurs after another more critical event.

Description

F3h = SMI Timeout

06h

[7] Event direction

0b = Assertion Event

1b = Deassertion Event

[6:0] Event Type = 03h (“digital” Discrete)

[7:6] – 00b = Unspecified Event Data 2

[5:4] – 00b = Unspecified Event Data 3

[3:0] – Event Trigger Offset = 1 = State Asserted

1. Check the SEL for any critical interrupts, memory errors, bus errors, PCI errors, or any other serious errors.

2. If these are not present, the system locked up before it was able to log the original issue. In this case, low level debug is normally required.
