User Zone / Help with diagnosing sudden computer shutdown

« on: January 30, 2025, 07:52:24 pm »

So my Blackbird system just suddenly shut down. I'd appreciate any help with diagnosing the issue. I found 3 high priority events logged by the BMC within 2 minutes of the sudden shut down. The messages are:

Code: [Select]

xyz.openbmc_project.Sensor.Device.Error.ReadFailure
CALLOUT_DEVICE_PATH=/sys/devices/platform/gpio-fsi/fsi0/slave@00:00/00:00:00:06/sbefifo1-dev0/occ-hwmon.1
CALLOUT_ERRNO=108
_PID=4791

Code: [Select]

org.open_power.Proc.FSI.Error.MasterDetectionFailure
CALLOUT_DEVICE_PATH=/sys/devices/platform/gpio-fsi/fsi0/slave@00:00/raw
CALLOUT_ERRNO=0
_PID=26801

Code: [Select]

org.open_power.Proc.FSI.Error.MasterDetectionFailure
CALLOUT_DEVICE_PATH=/sys/devices/platform/gpio-fsi/fsi0/slave@00:00/raw
CALLOUT_ERRNO=0
_PID=26873I see many similar "MasterDetectionFailure" messages in the BMC event log that don't seem to have caused issues before. I don't see any other "ReadFailure" messages though.
The BMC seemed to think the system was still running in the "Server power operations" section. A Warm reboot failed, but a subsequent Power on fired up the system again.
There were no messages in the system journal for 5 minutes before the shut down, and those messages were not errors and appear to be unrelated to the issue.
The system is connected to a UPS, and other computers connected to the same had no problems.

User Zone / Gentoo installation issue

« on: September 08, 2024, 03:15:28 am »

I have an NVIDIA GT710 that I'd like to get working with my Blackbird. After getting past the boot issue by disabling the nouveau module in Petitboot, I still can't get the card to work in the OS. I tried Fedora, Debian and Trisquel. Then, realizing that maybe the 4KB page size issue was affecting me, I decided to try Gentoo. I tried the Distribution (pre-built) kernel, but this also has a 64KB page size, and failed with the same errors as the others. So I compiled a kernel with the options that I thought best, but it won't boot with that kernel. The console output shows:

Code: [Select]

It appears that something is wrong with ld64, but I have no idea what. How should I proceed from here? I wondered about posting in the Gentoo forums, but decided to try here first.

User Zone / Unable to boot with NVIDIA GT710 installed

I have a Blackbird system in which I'd like to install an NVIDIA GT710. However, after installation, boot gets to the Petitboot menu, but then fails as it searches for boot options. The following is logged in the console:

I've tried with and without the "disable onboard video" jumper installed. The system boots fine with a Radeon HD5450 installed, and the GT710 works fine in another system. What could be causing this problem?
