Hello - 

 

I was hoping someone might be able to point me in the right direction. I've tried upgrading the OS to 6.8.2 multiple times and have the same issue each time. When I login post reboot following the upgrade, the system cannot see my western digital drives. All the others are seen. When I revert back to version 6.6.6 the drives are visible and everything is back in order. Did something change in 6.8.2 that I need to update in my config? 

 

I'm the first to admit that I am a novice when it comes to this, but please see attached for the diagnostic file. 

 

Any tips or pointers would be greatly appreciated!

The problem isn't the WD disks, it's the Marvell controller they are connected to, this can sometimes help.

 

P.S. Your flash drive is showing some read errors:

Try chkdsk first, but it might be failing.

 

 

Thanks, johnnie.black! That did the trick. I inserted the "iommu=pt perimeter (see code below) to the /syslinux/syslinux.cfg file and things seem to be working. Really appreciate the response!

 

append initrd=/bzroot iommu=pt
