 |
|
I have a RTL8822BE WiFi card in a laptop here. It worked well on the install minimal CD, Genkernel of course. It also works when I run Genkernel myself, but I want it to work with gentoo-kernel-bin. In case it is related, this is an older laptop without UEFI, so I am doing a legacy MBR install.
When I boot into Gentoo, it works for a couple minutes but then the device disappears. Then I get the following error in logs:
| Code: | | Direct firmware load for rtl_bt/rtl8822cu_fw.bin failed with error -2 |
I can try to load the rtw88 firmware with modprobe, but it doesn't help. I can't get the module reloaded without a reboot.
It is an old laptop with poor thermals and tends to lock up during longer compilations, so I want to use gentoo-kernel-bin. I am hoping to find a solution that allows me to use this WiFi adapter with the pre-compiled kernel. Is this possible at all, or must I use Genkernel/manual kernel?
I found this thread trying to research the problem, but unfortunately it didn't pertain to my current situation in a helpful manner.

You got error with number two:
#define ENOENT 2 /* No such file or directory */
So, kernel can't find 'must have' file. But don't worry, it is easily to fix it.
We need just download linux-firmware.
Binary version of gentoo, can be very problematic with drivers.
I would to buy new device for gentoo, if I was on your side. |

| Thank you for your reply. Unfortunately, I already have linux-firmware, so I fear I may not be able to use this card if I insist on using a pre-compiled kernel. |

Thanks for the hint, pietinger. 
In fact I had dracut in my USE flags, but not initramfs - I shall do this. |
