  • I think you are onto something here. I was having the same problem when i needed to replace my usb. I turned off virtualization support and was able to boot.   I went further, the kernel pan

  • Thankyou very much for sharing this! It worked perfectly 🙂   I just upgraded my R710 server from 6.9.2 to 6.10.0-rc5 and ran into this exact same issue. Server wouldn't boot due to a checksu

    I have isolated the problem to be something with the hardware virtualization that is used by UNRAID to support VMs. I started by resetting my BIOS on my T610, created a fresh USB install and booted 6.

I too can confirm that this fixed my issue when updating from 6.9 to .10

 

mellanox give an explanation on what they do. If anything it’s a performance boost

We have all been turning iommu on here. 
 

how are we all affected by the 6.10.2 upgrade released today? It mentions intel IOMMU stuff?

 

I don’t understand if we need to worry or not?

 

THIS

I too am having this issue on my dell R710.

 

I updated to 6.10.2 to see if there was a fix and now i get a bzfirmware checksum error. I just ended up going back to 6.9.2 until there is a solution to this.

 

Unless someone has a fix for this i would not recommend updating to 6.10.2

Did the boot arguments not work for you? I’m able to boot on both an R710 and R720 for the 6.10.x versions after adding them.

On my Dell R710 I too added the ARG and it will not boot. Still get the checksum error. It took 3 reboots to finally work.

I have the same issue just with a R410. I've tried rebooting a few times and it doesn't want to start.

I am having a similar issue with my Dell R610 upgraded to latest and now getting checksum error with the append inserted. Any advice would be greatly appreciated.

You can always try manually updating - maybe its a legit issue.  Download the zip file from https://unraid.net/download, overwrite all of the bz* files (and the changes.txt file) on the flash drive with those in the zip.  Reboot and try again.

This was the only method that worked for me. Thank you!

How do I get this intel_iommu=on iommu=pt to remain remain on boot? I run a headless unit and every reboot I have to drag the monitor out and boot with those options.

@Squid overwritting the bz files on the USB did not help for me. Only using those options on boot allow UnRaid to boot.

 

Is downgrading to 6.9 as simple as overwritting the bz files with the 6.9 versions?

Edit the boot menu at Main - Boot Device - Flash - Syslinux Configuration

Goto main click on flash drive and in the syslinux settings add to end of the append line for your boot option. or install 6.10.3rc1 as it is the default.

You should update to v6.10.3-rc1, iommu=pt is the default, re-enable VT-d in the BIOS if disabled.

I'm on Version 6.10.3 2022-06-14. My start up syslinux.cfg:

label Unraid OS
  menu default
  kernel /bzimage
  append pcie_no_flr=1022:1487 initrd=/bzroot video=efifb:off acpi_enforce_resources=lax pcie_acs_override=downstream

 

I don't have the recommended settings, although what brought me here was the same error message as the OP.

intel_iommu=on iommu=pt

 

Eventually, what worked was this:

Its not clear if the recommended settings should be added to my boot profile? I'm using a 5950x processor.

Just wanted to add that this doesn't just apply to Dell servers, I've been having issues booting my flash on my HP DL380p Gen8 machine for months, to the point I changed out all my usb keys, and have to do all updates by hand (and attempt to boot them a dozen times or more till it just happens to work).  Added the lines above to my syslinux.cfg file, and it boots every time.  As long as updates don't rewrite the syslinux.cfg, it should survive updates now too (haven't been able to do an automatic update since the 6.10.x series started in RC...).

Lines above won't so anything since v6.10.3, it's already the default.

It ended up failing again after 3 reboots.  Those lines aren't in my syslinux.cfg.  It's definitely not my usb keys (I've tried many, and even bought new Samsung brand keys).

They don't need to be starting with v6.10.3, like mentioned it's the Unraid default now.

Hello, 

Reporting to this thread regarding this concern as well
UnRAID 6.11.1

Today I was going through my plugin check and (2X) plugins were not updating, they would sit in a 'pending' state 
Unassigned devices 
Unassigned devices Preclear 

I did check the logs before the reboot regarding this so my next course of action was to reboot (I would post the logs of the above plugin errors, however logs are not written to the flash and only to the RAM disk so I can't) going to look into how to possibly resolve that concern if there is a way to capture logs.

 

Upon reboot I did receive a checksum error 

bzroot-gui - checksum error .... PRESS ANY KEY TO REBOOT

 

I turned off the system and inserted my USB flash into my local desktop
Downloaded > unRAIDServer-6.11.1-x86_64.zip

Copied > bzroot-gui & bzroot-gui.sha256 (from the above zip to the flash drive)
Safely removed the flash disk

Inserted the flash disk back into my UnRAID server
Booted with success
Plugins updated with success

 

Posting feedback in case anyone else has these concerns.

 

Thank you,

I was pondering that.
was going to wait until everything got buttoned up, regarding some of the feedback on


I am still running V2 for now.
I will push up to the latest soon. I appreciate that recommendation.

Thank you.

I updated unraid 6.9.2 to 6.11.5 and got the same error.


The server did not start after the update and gave me a superblock error.

I couldnt get into the server remotely anymore.


The device that gave me the error unraid /dev/loop0 /boot/bzmodules error


I had to remove the USB from the server and opened it on a laptop.


The loop0 seemed to be the bzmodules.

So I copied the content of my flash-drives previous folder over the files on the USB.

 

Put the USB in the server, started.


At boot the server download/written a file or 2.

And then the server started as before.


This fixed the error for me.


Still cant update to 6.11.5 succesfully
