On a Ryzen 5 3600 desktop with two nvme drives running windows 10 & Ubuntu 22 unaware of each other it is 50-50 odd of either Bluetooth or WiFi not detected until a few reboots

Windows regularly puts and leaves radios in various low-power states that linux doesn't know about, so I generally need to cleanly shut down windows completely before booting into linux.

Earlier quoted context omitted.

Could you please give the dmesg and/or other relevant id for your Realtek device? I'm getting tired of these Intel ax2?0 issues. I'm not much of a Bluetooth user but does it also work well?

I'm currently logged into Windoze for some work but I can tell you the card is a Realtek RTL8852AE. I can pull up the dmesg info later tonight when I reboot into linux if you want. Bluetooth works fine on it on Linux as well between my phone and my Sony headphones. No complaints from me on Fedora/Opensuse. Out of curiosity, what issues are you having with the Intel AX chip? I also have it on my Lenovo Intel work mach…

No that's fine, great info, cheers.

Ironically, I run a machine with a Realtek Wifi 6 chip and it works great on Linux, despite everything I read online was that Realtek is to be avoided on Linux and Intel should be the go-to. In a similar fashion, I was also luckier with Nvidia proprietary drivers on Linux than with AMD open source drivers. Seems like HW on Linux really is a box of chocolates, you never know what you're gonna get.

do you by chance have any experience with the realtek ethernet? I too have seen the conventional wisdom around avoiding the realtek chips. I'm looking to build a linux box (hopefully) soon and filtering out mobos with realtek chips is difficult

I'm so relieved to find that its not just me going crazy all this time. Its gotten so bad that I've had to install a bloody MediaTek WiFi card in my ThinkPad just to make it work reliably.

I remember when the 8000 series radios were the gold standard for mobile wireless, all the newer AX cards have been nothing but pain and suffering.

The link seems to be experiencing a mysterious outage, reporting "404" when I visit the page. Other bugs seem to be fine. Not sure what's going on. Here's a mirror: https://web.archive.org/web/20230317164517/https://bugzilla....

The admins probably got grumpy because a bajilion HN bots querying for link previews DDOS'ed the whole bugzilla.

Hug of death from HN visitors.

For fellow website admins, this is your regular reminder to use static site generators, where possible, and server-side cache where not.

I posted this solution elsewhere recently:

I think it is what you've been seeing.

I’d argue SSG and caching are the same solution just a difference in where the cache resides (disk vs memory) and warming strategy (on-demand vs preemptive)

Is there a patch for the kernel 6 line to add back the lar_disable functionality?

They used to be glitchy, I've had okay success with them. The igc module (new igb) is a buggy nightmare on Linux with the kmod maintainers having no idea how to run a speed test with forwarding to also kernel panic... It's really bizarre.
