+ [Fix]
+ 
+ Commit 54b4fda5a761 ("iwlwifi: mvm: Read acpi dsm to get unii4
+ enable/disable bitmap") is required to fix this issue. The other commit
+ is pulled in for dependency.
+ 
+ [Test Case]
+ 
+ Install a prebuilt kernel with these fixes, put DUT under idle for 5
+ mins and check if there is still firmware error messages.
+ 
+ [Where problems could occur]
+ 
+ There is little chance that it can ever go wrong judging from the
+ simplexity of the two commits.
+ 
+ [Other Info]
+ 
+ While the two patches have already been included in mainline and
+ therefore Ubuntu unstable, only oem-5.13 and impish are nominated.
+ 
+ ========== original bug report ==========
+ 
  After applied patches from bug 1933938 to enable AX201 on ADL platforms,
  some of them may still fail to functioning stably due to fw error when
  LARI_CONFIG_CHANGE command is sent. With CONFIG_IWLWIFI_DEBUG turned on,
  following error appears:
  
-   iwlwifi 0000:00:14.3: iwl_mvm_lari_cfg sending LARI_CONFIG_CHANGE, 
config_bitmap=0x8, oem_11ax_allow_bitmap=0xf
-   iwlwifi 0000:00:14.3: iwl_trans_txq_send_hcmd_sync Attempting to send sync 
command UNKNOWN
-   iwlwifi 0000:00:14.3: iwl_trans_txq_send_hcmd_sync Setting HCMD_ACTIVE for 
command UNKNOWN
+   iwlwifi 0000:00:14.3: iwl_mvm_lari_cfg sending LARI_CONFIG_CHANGE, 
config_bitmap=0x8, oem_11ax_allow_bitmap=0xf
+   iwlwifi 0000:00:14.3: iwl_trans_txq_send_hcmd_sync Attempting to send sync 
command UNKNOWN
+   iwlwifi 0000:00:14.3: iwl_trans_txq_send_hcmd_sync Setting HCMD_ACTIVE for 
command UNKNOWN
  
  Then begin FW error, hardware reset:
