[6.9.0] Won't boot after 6.8.3 to 6.9.0 update

it seems that the unraid nvidia caused issue (source : os update assistant). after uninstall it, the update assistant conclude "No issues were found with your server that may hinder the OS upgrade. You should be good to go"

ALL WORK

I've have an issue with the microcode that's in bzroot causing it to hang at "bzroot... OK".  Running on a Supermicro X10 MB with a Xeon E5 V3.

 

If you want to try without the microcode, after installing the 6.9 update via the GUI, run the following commands before rebooting.

 

cp /boot/bzroot /boot/bzroot-orig
dd if=/boot/bzroot-orig bs=512 skip=$(cpio -ivt -H newc < /boot/bzroot 2>&1 > /dev/null | awk '{print $1}') of=/boot/bzroot

 

Those commands will strip out the microcode.

All works with your commans....

 

Thank,

Changed Status to Solved

If I want to install version 6.9.1, am I better off running the commands again, before rebooting ?

 

Thank,

Why did you suspect microcode to blame?  Have you seen other reports of this on the web?

Based on SeeDrs response, I ran these commands and the 6.9.0 install worked.

cp /boot/bzroot /boot/bzroot-orig
dd if=/boot/bzroot-orig bs=512 skip=$(cpio -ivt -H newc < /boot/bzroot 2>&1 > /dev/null | awk '{print $1}') of=/boot/bzroot

otherwise the boot froze at / bzroot ... OK

 

For 6.9.1, I just want to know if I would be better off doing it to keep myself out of the problem.

I would rather want to find out why installing microcode update prevents boot.  Make sure your motherboard bios is up to date.

 

I just saw, it's not up to date, I have the penultimate version (one month before).

I don't think it makes a difference.

 

I just don't want to have to go back to 6.9.0 after.

 

Can I run these commands to avoid (in prevention) the problem?

Sure, it's your server.  But there are reasons Intel goes to great lengths to produce firmware updates.

I don't even know what these commands do.

but it made the update from 6.8.3 to 6.9.0 work

 

My question should have been, what are these commands for?

 

Subsequently, I will update my bios.

The microcode of the CPU ? or what ?

Why the update block without these commands ?

 

How can I correct the problem? Just update the bios ?

 

Thank,

Yes.

 

I would do as Tom suggests and update your BIOS.

I run UNRAID in a VM with GPU Passthrough where hypervisor.cpuid.v0 = FALSE.  I think the issue for me is that microcode cannot be applied to the CPU through a virtual machine causing it to hang.

 

When hypervisor.cpuid.v0 = TRUE there is no issue applying the microcode. I guess it's able to detect that it's a virtual machine and actually doesn't apply the microcode.

I wanted to update my bios, it's already up to date !

I had to manually stop the server, it was jammed at "Stopping emhttpd", anyone know why?

 

Thank,

Is there a way to reflash the bios, to be sure?

 

Any idea for my server which does not reboot with the emhttpd?

 

Thank,
