At least the laptop still boots. I booted from the Ubuntu USB stick and copied rtw8822c_fw.bin.zst rtw8822c_wow_fw.bin.zst reboot into Debian and renamed /lib/firmware/rtw88 rtw8822c_fw.bin to rtw8822c_fw.bin.orig rtw8822c_wow_fw.bin to rtw8822c_wow_fw.bin.orig copied the rtw88c*zst files to /lib/firmware/rtw88 and unzstd rtw8822c_fw.bin.zst unzstd rtw8822c_wow_fw.bin.zst reboot and it looks like the 9.9.15 firmware loads but wifi is still broken :( $ sudo dmesg | grep 8822 | more [ 4.324839] rtw_8822ce 0000:02:00.0: enabling device (0000 -> 0003) [ 4.325612] rtw_8822ce 0000:02:00.0: firmware: direct-loading firmware rtw88/rtw8822c_wow_fw.bin [ 4.325622] rtw_8822ce 0000:02:00.0: Firmware version 9.9.4, H2C version 15 [ 4.325648] rtw_8822ce 0000:02:00.0: firmware: direct-loading firmware rtw88/rtw8822c_fw.bin [ 4.325649] rtw_8822ce 0000:02:00.0: Firmware version 9.9.15, H2C version 15 [ 4.424742] Bluetooth: hci0: RTL: examining hci_ver=0a hci_rev=000c lmp_ver=0a lmp_subver=8822 [ 4.425746] Bluetooth: hci0: RTL: loading rtl_bt/rtl8822cu_fw.bin [ 4.426201] bluetooth hci0: firmware: direct-loading firmware rtl_bt/rtl8822cu_fw.bin [ 4.426224] Bluetooth: hci0: RTL: loading rtl_bt/rtl8822cu_config.bin [ 4.426295] bluetooth hci0: firmware: direct-loading firmware rtl_bt/rtl8822cu_config.bin [ 4.446717] rtw_8822ce 0000:02:00.0 wlp2s0: renamed from wlan0 [ 44.734789] rtw_8822ce 0000:02:00.0: firmware failed to report density after scan [ 47.890293] rtw_8822ce 0000:02:00.0: failed to send h2c command [ 47.893324] rtw_8822ce 0000:02:00.0: failed to send h2c command [ 49.974705] rtw_8822ce 0000:02:00.0: firmware failed to leave lps state [ 51.894806] rtw_8822ce 0000:02:00.0: firmware failed to leave lps state [ 51.898193] rtw_8822ce 0000:02:00.0: failed to send h2c command [ 54.134727] rtw_8822ce 0000:02:00.0: firmware failed to leave lps state [ 54.138153] rtw_8822ce 0000:02:00.0: failed to send h2c command [ 54.141249] rtw_8822ce 0000:02:00.0: failed to send h2c command [ 54.144316] rtw_8822ce 0000:02:00.0: failed to send h2c command [ 55.926858] rtw_8822ce 0000:02:00.0: firmware failed to leave lps state [ 55.930109] rtw_8822ce 0000:02:00.0: failed to send h2c command I don't remember those Bluetooth log msgs from before, so let me try copying all of the rtw88/*8822* files over to the laptop and try again..
