Hey there,
This issue keeps on cropping up, I cant find a trigger, I'll just be doing my thing and this will happen
HDD is a 120gb Samsung SSD, I've checked all the physical connections and it seems alright. This only happens with my arch install.
Once this error comes up, I need to reboot because nothing can find the root file system

SError: { HostInt PHYRdyChg 10B8B DevExch }
DevExch : Device presence has changed
This indicates that somehow all your sata devices loose connection.
Cause can be hardware or software.
If hardware the sata controller or mobo chipset/memory are possible candidates.
please post full dmesg, fdisk -l (as root) .
I'd also suggest you run a memtst (from archinstall iso or any other live disk)

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

Memtest came up clear.
man this is driving me crazy, doesn't happen in windows... Or if it does I dont notice it and its not logged in the event viewer.

Googling some of the lines from your dmesg finds lots of older (1-2 years) posts with similar errors, many involving Samsung SSDs. OTOH, none involve multiple drives dropping simultaneously AFAICT.
Still, a few things that popped up frequently were disabling laptop-tools and powersaving stuff, and booting with kernel parameter libata.force=noncq. Keeping in mind the threads were old, these things might be worth a try.
But whether the Constitution really be one thing, or another, this much is certain - that it has either authorized such a government as we have had, or has been powerless to prevent it. In either case, it is unfit to exist.

Then, another kernel commandline option to try is e.g.:
acpi_os_name="Windows 2006"
Just in case your BIOS is doing silly things, depending on the OS it thinks it detects

Thanks guys.
I've tried the kernel options to no avail. All power saving options are off in both arch and the bios. I'm temporary going back to windows because I need a working, stable computer but will keep trying to solve this.
Thanks for all the help guys

You should post more information about your hardware as it could help narrow down the problem or help steer you in the right debugging direction.
See this [1] for an example of why it might be important to know all the details about the hardware. It's just an example, it might not apply to your case in particular.

I've discovered the problem and its mechanically unsolvable.
This is a picture of my MB (I know its not great, I bought it in case I wanted to try OSX, which I never ended up doing because I found arch)

As you can see, the SATA ports are directly under the 2nd PCI-E slot. When I had my 560ti inserted for my gpu-passthrough, it would put pressure on the top of the sata cables and I guess that causes issues. Since removing the card and reinstalling arch the problem has subsided. It returns if I reinsert the card.
What a bummer :<

I have some SATA cables with right-angle plugs on one or both ends. Could you use one of those on your MB?
Something like this: http://www.newegg.com/Product/Product.a … -12-123-10
How to post. A sincere effort to use modest and proper language and grammar is a sign of respect toward the community.

It would take some 135° angle plugs, not 90°. I'm not sure if such exist.
Pressure on cables doesn't quite explain how all 5 of them lose connection at the same time when (probably) only 2 are touching the GPU. I think it's more likely to be EMI or software bug (something with IOMMU?). I suspect it may go away if you leave the 560Ti inserted, but unpowered.
Your log isn't complete, btw. All SATA links are reestablished and everything should continue running. There must be something more happening later that isn't logged. You probably posted logs read from disk after reboot, right? Obviously, all you can find in such logs is events that happened before disks had been really lost for good. Run dmesg -w |tee /media/some-pendrive/some-file to have kernel errors printed on the screen and written to pendrive in real time, if you want to know more what's going on.

Those cables should solve the problem if it's really mechanical and from the graphics card pressing on stuff. The price is annoyingly expensive but this is the only SATA data cable I've seen with a shape like that.
