System specs:

Asus Z9PA-D8 motherboard with:

2x E5-2670 (0) 

8x 8gb samsung ECC ram

4x intel 160gb ssd 

 

So after the problem of booting the system, which was miraculously solved by removing all ssds and 1 gpu, manually set IP etc, we have another problem:

 

I get 100% CPU usage on 1 core. De culprit is udevd. DIagnostics are attached.

Also attached the dmesg output.

 

Thanks in advance for any help!

So I did some troubleshooting. Tried to install Proxmox tot test if its a hardware issue. It install fine, only after it wont boot properly giving me tons of errors.

Udevd manages hardware, so it thought: lets try and use LSI Megaraid controller instead of the intel one.

So i got the manual to see which jumper I had to change. The manual says that the intel controller is for windows use only and thus i changed from the intel to the LSI controller.

But now we have ANOTHER problem. The LSI Megaraid doe not find ANY drives. I tried mechanical drives and SSD's, none of them show up. What could this be?

Anyone a clue? I already did a BIOS update..

If you suspect a hardware problem, you should probably start with a memtst  (on boot menu)  for about 24 hours. 

Memtest Comes Out with no errors..
I suspect my PSU... Very strange values if i boot into windows with. Hardware monitor..
So should.probably order one! Thanks again for your help Frank

I found with google by searching with the term    udevd high cpu usage

 

Not sure if this is your problem but I suspect that you have some device connected to your server that  a device driver can't be found for.

Beat you to that one Frank! I disabled onboard sound and VGA, removed one GPU, disconnected EVERYTHING even sata drives disconnected the usb "hub" from the front of the case...
Only thing I could do is disable all but nic..

I kept searching and indeed one other guy reports the CPU bug error on booting RHEL and proxmox. His psu was at fault.
Although I find this strange.. installing windows resulted in zero problems.. even a prolonged stress test didn't crash it.. so... Guess i should try using a different psu.
Have only 500 watt units laying around.. should be enough without the gpu's...
