The 3ea board is booting well,

but 3 board meet BIOS_RESET_CPL crash when booting up.

But it is booting well as below scenario.

 

1. The board is booting fail in BIOS_RESET_CPL.

2. The power is off and power on in 5 seond.

3. The box is booting well to shell.

 

And it is booting fail as below scenario.

 

1. The box is booting well to shell

2. The power is off and power on after 2 minute.

3. The box is booting fail in  BIOS_RESET_CPL.

 

I don't know which part to debug? (hw issue or bios issue)

Hello Jean

Does your comment mean to re-register at Intel Premier support -> Create New Case?

Anyway, I have one question.

For 3ea of bad sample, I modified the setup menu as below.

Advanced -> Power & Performance -> CPU - Power Management Control
Intel(R) SpeedStep(tm) - Disable
Intel(R) Speed Shift Technology - Disable
C states - Disable

And I tested power on/off in 3ea sample.
It is working well.

I have my doubts.
The above three options are related to power management, and if it is disabled them, booting will be fine.

Jean
Can you explain what is wrong with my board regarding this phenomenon?

 

Many thanks
