Issues with Realtek USB network dongles?

English Hardware
1

Having all sorts of issues with “what appears to be” my Realtek USB Wifi dongles recently (think I have almost tied it to the dongles…)
One of them gives me a “kernel bug” on boot - see here - and the other is doing multiple weird diskchecks on boot, eg
image
that either never end, or if they do, then can’t seem to login (and exceptionally slow…)
The 2 dongles are:

ID 0bda:b812 Realtek Semiconductor Corp. RTL88x2bu [AC1200 Techkey] 
ID 0bda:b82c Realtek Semiconductor Corp. 802.11ac NIC

It’s a multiboot system, no issues with any other OSs. And these seem to work when plugged in “after the fact”, is only a boot issue? Have another based on MT7921AU that is fine.

Tumbleweed Latest / Plasma Latest / 16GB RAM / Lenovo M920S

Sorry, I seem to be asking a lot of strange questions recently, but these have had me baffled!! (Already reinstalled once… :roll_eyes:

Thanks.

You use the buildin rtw88 driver?

So open a bugreport.

Or try the 3 rtw88 from here:
[rtw88_8822bu](https://download.opensuse.org/repositories/home:/Sauerland:/hardware/openSUSE_Tumbleweed/)

Or the 2 rtl8822bu from the above Repo.

I have the same Realtek USB dongle (RTL88x2bu) and experienced the same crash, starting after the update to kernel 7.2.x.

I don’t know what the problem is, but it’s not the kernel module, at least for me. I can boot the system with no suitable kernel modules (rtw88_8822bu or 88x2bu) and the system will still crash (it becomes gradually but quickly unresponsive). I also found that the system would boot and work normally if I unplugged the dongle, but once I plugged the dongle back in, the system would become unresponsive after a few moments.

I “fixed” the problem by using a custom kernel (I used the so-call XanMod kernel). No crashes, and you can use either the included “rtw” module or the 88x2bu, which I find gives a little bit faster speeds.

I concluded that it was one of suse’s custom patches that was the problem. Maybe this is the case, maybe not.

So open a bugreport is the best way…

Can you tell me how or to whom I should submit it?
