I have decided to try to eliminate some things. I ended up formatting my RAID drives and cleared that out. I also rebuilt the RAID Array in hopes of clearing up this issue. But these did not fix what we are seeing here.
As to your request regarding selecting versions from the GRUB menu, I tried the two versions of the kernel that I have installed on this server. The two kernels are: 4.15.0-20-generic 4.15.0-23-generic This is an interesting development. When I booted the earlier version (4.15.0-20), I do not get any errors. I tested several large copies to a USB drive with no issues. 6 Times I tried to create the issue, but was not successful. When I booted back to the new version(4.15.0-23), it errors almost immediately. When I went and rebooted back to 4.15.0-20 it errored as well. So the issue is systemic in both releases. I will try the updated kernel next. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1777586 Title: Ubuntu Server 18.04 LTS aacraid error Status in linux package in Ubuntu: Incomplete Status in linux source package in Bionic: Incomplete Bug description: I upgraded from a previous version of Ubuntu 14.04LTS to 18.04LTS and am now running into these raid adapter driver errors. The server ran fine in older version. My apologies as I lost the exact version, but it never had any errors like this version. Now when ever I try to copy files to the RAID 5 drive, or untar a file, I get these errors now after a few MB's of written data.

I loaded in Debian9.4.0 and it only briefly showed this error once. But appears to be much more resilient and appears to work fine.
