Some nominal tasks would remain in an actual emergency, such updating Conky configurations.Д«oth systems are notably slower than the office desktop. At this stage I presume one or both cards will function as expected. In an temporary emergency I could get by with only one card. I am not pulling apart the office desktop to test.

One component I did not test is the two digital TV capture cards. I repeated the tests with the ASRock with the same results and remedies. Using a sledge hammer and disabling the drive in the BIOS resolved the nuisance. Thereafter I was greeted with another useless message:Д«lk_update_request: I/O error, dev fd0, sector 0ДЄdding blacklist floppy had no effect. Likewise thereafter rebooting with the clone disks. Curious, I connected an empty IDE/PATA hard disk and booted with a live USB stick. The lack of both device nodes are not show stoppers for a temporary replacement system.

Many years have elapsed since using a floppy disk drive that I pondered how the system is supposed to behave. The test system does not have a floppy disk drive but has a motherboard floppy disk controller. I wondered if that contributed to the mystery.

The optical drive manual eject button functioned as expected indicating available power. There was no /dev/sr0 device node for the optical disk and no /dev/fd0 for the floppy disk. Why did I see this message with an AMD CPU? Digging around the web indicates certain AMD CPUs do use the lfence instruction. Adding nospectre_v2 to the boot configuration stopped the message. Spectre V2 : Spectre mitigation: LFENCE not serializing, switching to generic repoline I was greeted with a useless boot message: That the file exists is not an issue as these days I avoid motherboards with Nvidia video chips, which is why I had not noticed the block file. I found a remnant block list file in /etc/modprobe.d for the nouveau driver. The kernel did not toggle into framebuffer mode. The network controller initialized as expected. I booted into runlevel 1, deleted /etc/udev/rules.d/les, and rebooted. I installed the clone disks into the Asus M3N78-EM clunker. The other system is an ASRock N68C-GS4 FX motherboard with a GeForce 7025 GPU, AMD BE-2400 2.3 GHz Dual Core CPU, and 4 GB of DDR2 RAM. One system is an Asus M3N78-EM motherboard with a GeForce 8300 GPU, AMD 5050e 2.6 GHz Dual Core CPU, and 8 GB of DDR2 RAM. Both systems now are nominal test systems, mostly collecting dust in the office. At one time both systems were active in the home LAN. I have two older computers that could be used as temporary relief. The next disaster recovery test is losing the office desktop, including both internal disks. If the first disk failed then I could restore files from the second internal disk backups and lose only data changes made in the most recent hour. In a real disaster with the second internal disk I would lose three days of backups but not lose data files because the data are stored on the first disk. The test is straightforwardВ - shut down the office desktop and replace the disks. One possible disaster is losing one of the internal disks. The second backup layer includes cloned disks of that system that are synced every three days. Sometimes to compare changes made to files and sometimes to restore fat finger mistakes. I test those backups several times each week. The first layer of backups is hourly backups to a second internal disk. The most critical system is the office desktop that also is the home LAN file server and hosts all virtual machines. Nonetheless I wanted to test some disaster recovery with the home LAN. Generally, unlike proprietary operating systems, moving hard disks from one Linux system to another usually is seamless and presents few disruptions.
