[Solved] H12SSL-i, BMC resets after some time

[trumee]

Hello,

The BMC in my motherboard reset after a few minutes. The logs shows a repetitive sequence of,

• [MEL-0131] iKVM was launched successfully
• [MEL-0212] The fullsmbios file was uploaded successfully
• [MEL-0056] BMC was reset successfully
• [MEL-0132] iKVM was closed successfully

The firmware versions are,

• Firmware version: 01.04.03
• Firmware Build Time: 03/13/2024
• Redfish Version: 1.11.0
• Bios Firmware version:3.3
• Bios Build Time: 03/28/2025
• CPLD Version: F0.A6.47

I suspect the BMC reset is due to 'fullsmbios' file being uploaded. I dont understand why that is happening though. Is there a way i can fix this?

Thanks

something press the unit ID button in the IO shield area ?
and/or BMC VRM overheating (tiny things, board need steady airflow)

I dont see any init ID button in the IO shield area. Is that present in H12SSL-i motherboard?

Are the tiny things around the ASPEED BMC chip? I am running the system with an open case.

This is the temperature readings,

ooh i was wrong. supermicros UID switch can not reset BMC as on other vendors.
so the issue should be the BMC VRMs are broken or overheating.
what motherboard revision do you have ?
if very early one SM may replace it.

EL-0212] The fullsmbios file was uploaded successfully << localhost, the board it self, normal BIOS report.

does the IP 172.17.1.122 belong to you ?

I suspect the BMC reset is due to 'fullsmbios' file being uploaded

the "BMC was reset successfully" is normaly shown after execution of IPMICFG/ipmitool/ipmiutil reset commands.

This was it!

I had a script which was controlling the fans and it was causing the bmc to be reset. I have now disabled the script and am not seeing bmc resets.
