Hi, [ 16.768409] iwlwifi 0000:01:00.0: WRT: Invalid buffer destination [ 22.545080] iwlwifi 0000:01:00.0: WRT: Invalid buffer destination [ 22.892104] iwlwifi 0000:01:00.0: WRT: Invalid buffer destination This error happens on every boot. It was reported by Len Brown back in November, but is still present in v6.11-rc2. In that exchange, Benjamin said "quite likely it should just be hidden unless the IWL_DL_FW debug flag is set (i.e. use IWL_DEBUG_FW)". The cause of the error appears to be a firmware regression rather than a kernel regression. It does not happen with iwlwifi-ty-a0-gf-a0-73.ucode but does happen with iwlwifi-ty-a0-gf-a0-74.ucode onwards. (I found these details in the Debian bug report and have verified that this is accurate using a v6.5 kernel). There are many bug reports for this error elsewhere (Debian, ClearLinux, etc.). Is it an actual error? Or just an erroneous message that should be hidden?
