Here is the output Comrade. Appreciate your perusal.

Ok there is actually some interesting stuff in here but as predicted, nothing actually "wrong" and certainly not any obvious runaway problems that would indicate storage subsystem issues.

Well that's a good start. Don't use root by the way, sudo exists for a reason.

These are all just noise from a buggy BIOS ACPI implementation - you see these on a lot of modern machines and it's nothing to worry about. Are you booting in BIOS or UEFI mode by the way? Switching to UEFI makes most of this stuff go away as well as being the correct way to run a computer in the 21st century.

Nothing to worry about - looks like it might be a serious failure to load wifi firmware but I imagine your wifi is working just fine. If not, now you know why it isn't. See:

Virtualization is disabled in your firmware. This isn't technically a problem if you don't ever use hypervisors but it really should be on: technology increasingly calls out to low level stuff like this and presumes it will always be there. Not a problem for you but Win10/11 require this feature to be enabled for things like WSL, WSA, Virtualization platform features, Security Isolation, etc.

These last two aren't worth worrying about as they are minor glitches in subsystems you aren't using and don't care about. Bluetooth and PipeWire are working, just certain bits of them aren't. That's just log noise so discount it.

In short, except for some easily explicable error messages relating to system firmware (ACPI, Virtualization) and perhaps the poor choice of BIOS vs UEFI your system has a completely unremarkable and clean error log.

There is nothing wrong with your computer. Presuming it's still working of course.

Now you could dive way deeper - you haven't posted the SMART log from the SSD let alone started logging and tracking disk perf stats or examining scheduler behaviour. And trust me please: you don't need to.

THERE IS NOTHING WRONG WITH YOUR COMPUTER.

The flashing case light is symbolic. It's not actually locked in a one-to-one relationship with disk access you know. Funnily enough your eyes couldn't keep up with the 400-550k IOPS an off the shelf SSD is capable of - and neither can any LED strobe that quickly. You are not actually 'seeing' anything other than a vague courtesy indicator from the system firmware that interposes itself between the access patterns of your storage subsystem and a 0.01p LED on the end of a wire that "stuff is happening". That's it. Your logs are clean and presuming the system works and your SMART data is ok you're worrying about nothing.

Simon's advice is solid: if it's bugging you, cover it up - or just disconnect it.

I am willing to be ANY money that over the next few weeks and months the pattern of that LED activity will change randomly and repeatedly. In 4 weeks you'll see a different pattern and will have completely forgotten this entire episode!
