After updating my openSuse Tumbleweed on 2023-03-18, I found that my Wifi card
was no longer found.
I traced it down to a problem with loading the firmware file:
# dmesg | grep rtw
[ 5.092426] rtw89_8852be 0000:03:00.0: Direct firmware load for
rtw89/rtw8852b_fw.bin failed with error -2

[ 5.093334] rtw89_8852be 0000:03:00.0: enabling device (0000 -> 0003)
[ 5.106477] rtw89_8852be 0000:03:00.0: no suitable firmware found
[ 5.106855] rtw89_8852be 0000:03:00.0: failed to recognize firmware
[ 5.107068] rtw89_8852be 0000:03:00.0: failed to setup chip information
[ 5.109638] rtw89_8852be: probe of 0000:03:00.0 failed with error -2
Booting from a btrfs snapshot from before the update left me with a working
Wifi. I noticed that in the update, the firmware file has been modified
(snapshot 5 is the one with the working Wifi):
From snapshot 5:
# cd /.snapshots/5/snapshot/lib/firmware/rtw89/
# sha256sum rtw8852*
...
147ece8abea92576a7cdb888f174422abb3b1265371c016e16093400934b9858
rtw8852b_fw.bin.xz
...
# From not working system after update:
# sha256sum /lib/firmware/rtw89/rtw8852*
...
0a1b68c540e5670c4e651802c7ecbd01bd045e98a4d36903aee494abde94b69f
/lib/firmware/rtw89/rtw8852b_fw.bin.xz
...
I could work around the problem by copying the "old" version of the firmware
file over the "new" version and reloading the rtl89 modules:
# rmmod rtw89_8852be rtw89_8852b rtw89_pci rtw89_core
# modprobe rtw89_8852be
# dmesg | grep rtw
[...}

After the reload, the Wifi was detected by NetworkManager, and I got a working
connection immediately.
