Tech blog, CVS entry, payload, version of software affected etc ? This could be super useful to help others protect against, not to mention that it's wild that a "pdf" can still do such damage in 2023.

how in the world does that puny mb vrm power a 13900K ? WHAT what's the catch ? What motherboard model / revision / version is it ? Come on Linus, give specs

Got a weird hissing rustling coil-whine-ish sound coming when windows 10 is booted but as soon as i boot a live linux there is zero noise in both the speakers, headphones, front or back connectors. Got a asrock x470 taichi https://www.asrock.com/mb/AMD/X470 Taichi/index.asp#Specification Tried the windows default drivers and also realtek's drivers to no avail. I notice the noise/hissing especially when moving the mouse, windows, or when some cpu intensive app/game starts processing I tested with both a set of 2.1 logitech speakers and a pair of sennheiser headphones connected to front and back. It's really annoying at times. I am now running my headphones/speakers via my nvidia gpu -> DP -> monitor and this one is much better tho has some noise if the display is >80% volume. I'm fine with how it is until i find a solution on my main soundcard. What can I do to make my windows pure silence be as good as linux's ? Do I even have a chance or should I just get a dedicated pcie card?

I have 3x 3.8TB nvme pcie3 enteprise ssds in raid0 (mdadm on linux) and i'm getting read speeds the same or below that of the individual underlying drives. These drives are rated at 2.4~2.5 GB/s sequential max read, so in a raid0 setup i should get more, but sometimes i get less. setup: Epyc 7502p 3x 3.8 TB Samsung NVME pcie3 ssds 128GB DDR4 Debian 10, stock, default kernel On the software side, mdadm raid0 from all three devices with xfs on top. no special flags passed to xfs creation, defaults only.

so it's normal, nothing to see here ?

Did i step on somebody s tail ? :) Bump

This would make sense. I'd like to get to the bottom of this, know any community where i could get some expert advice? (though that rarely comes free). If it's against the rules to post links to other forums, can you pls dm me ?

So i have my windows boot drive on a mirror composed of 2xsata 120gb ssds Do mirrored volumes trim/optimize automatically in windows or is this a bug ?

Very good points brought up by this video. Linus should do a vid on this too.

here's a screenshot of a real world problem : copying a game - for example - guildwars 2 from one drive to the other starts at around 2-300 MB/s then drops to 10. no other activities running in the background

do i have to install a driver from kingston or intel for their nvme drives ? like samsung has for it's 970 for example ???

Yep, makes perfect sense. to be thorough i even disabled the antivirus. So nope, nothing running in the background.

ah i forgot my system specs asrock x470 taichi ryzen 7 2700x 2x8GB gskill 3200mhz cl14 windows 10 latest updates

This one is the intel nvme drive: and this one is the kingston nvme drive: the results are all over the place. on paper, the kinston drive is faster. Intel: 1800 MB/s read and write (intel specs) Kingston: 2,200/2,000MB/s (kingston specs) I know bench and real use is not the same thing but 200Mb/s ? something wrong with my motherboard or os ? it doesnt matter if its steam verify or just copy a huge iso from one disk to the other. speeds are crap
