Description Michael Stoykov 2023-03-27 08:19:12 UTC 
Description of problem:

Running kernel 6.2.7 (or any 6.2.x so far) with a Realtek b852 wifi network controller gives:

> Mar 27 09:51:17 fedora kernel: rtw89_8852be 0000:01:00.0: no suitable firmware found
> Mar 27 09:51:17 fedora kernel: rtw89_8852be 0000:01:00.0: failed to recognize firmware
> Mar 27 09:51:17 fedora kernel: rtw89_8852be 0000:01:00.0: failed to setup chip information
> Mar 27 09:51:17 fedora kernel: rtw89_8852be: probe of 0000:01:00.0 failed with error -2

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Get a laptop wiht Realtek b852 (in thsi case hp elitebook 845 g9) 
2. Get kernel 6.2 + (as the driver was not in the kernel before that)
3. Get linux-firmware
4. boot - get no wifi working and the error.

Actual results:

Wifi card not being found at all

Expected results:

Working wifi


Additional info:

https://github.com/lwfinger/rtw89 does work (and worked with previous kernel versions. (for 6.2 you need to blacklist the kernel drivers though :( )

Given the actual problem and following the [note](https://github.com/lwfinger/rtw89) about firmware *fixes* the issue.

So downloading https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/rtw89/rtw8852b_fw.bin and putting it in /lib/firmware/rtw89/ fixes the issue.

But in the same directory there are already 3 files including rtw8852b_fw.bin.xz which is provided by `linux-firmware` but it seems to not work.
Comment 1 Peter Robinson 2023-03-27 10:52:31 UTC 
There was a problem with firmware upstream with dealing with newer versions of firmware and compatibility of the old ones, this will be fixed with the next upstream release, and there should be a patch coming to the stable kernels as well to deal with it.

    rtw89: 8852b: rollback firmware to v0.27.32.1
    
    Since the format change of 8852b firmware will break user space as
    discussion in threads [1] [2], I should rollback firmware to v0.27.32.1
    in original format.
    
    This patch is equal to revert two patches:
      7375bcff3ffd "rtw89: 8852b: update fw to v0.29.29.0"
      5148670daadc "rtw89: 8852b: update fw to v0.29.26.0"
    
    Then, re-add these two with new firmware filename rtw89/rtw8852b_fw-1.bin.

Comment 2 Michael Stoykov 2023-03-27 11:47:25 UTC 
Looking at the changelog from https://koji.fedoraproject.org/koji/buildinfo?buildID=2169294 it seems like 20230210-147 should work? as it will be from before the upgrade?
Comment 3 Peter Robinson 2023-03-27 12:07:59 UTC 
sounds about right, we'll have an update early/mid april that will pull in the the fix too, but downgrade in the meantime should also solve the problem.
