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,
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.
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.
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.
While the two patches have already been included in mainline and
therefore Ubuntu unstable, only oem-5.13 and impish are nominated.
