** Description changed:
+ [SRU Justification]
+
+ [Impact]
+
+ backport-iwlwifi-dkms has a few problems to prevent it from loading
+ either kernel modules itself or the runtime firmware correctly.
+
+ The first issue is "unknown symbol iwl_mei_is_connected" error at module
+ probing. This affects revsions >= 9241 where iwlmei module was first
+ introduced in commit 71e53a8aae59 ("mirror: multi-input commit"). This
+ can be addressed by cherry picking commit cc7d59edeeae
+ ("[BUGFIX][NOUPSTREAM] iwlwifi: bump min kernel version for iwlmei") of
+ rev 9255 that bumps iwlmei prerequisite kernel version to 5.14, and
+ commit 87dce6e9817a ("[BUGFIX][NOUPSTREAM] iwlwifi: iwlmei isn't going
+ to be merged anytime soon") of rev 9543 that bumps to 5.20. Therefore
+ this affects Impish & Jammy that currently have 9340.
+
+ The second problem is that even we addressed 9340 with aforementioned
+ fix backported, the iwlwifi module may still fail to load firmware that
+ is known fixed in at least 9580 that is being proposed. This would
+ affects Focal oem-5.14 as well.
+
+ [Fix]
+
+ Bump to 9580 that fixes both issues stated above.
+
+ [Test Case]
+
+ Compile and run against Focal oem-5.14/hwe-5.13/hwe-5.15 kernels, as
+ well as Impish 5.13 and Jammy 5.15.
+
+ [Where problems could occur]
+
+ While the revision number represents the commits since the git root
+ commit of backport-iwlwifi, this is going to back port more than a
+ thousand commits for Focal (8324 -> 9580) and 240 ones for Impish/Jammy
+ (9340 -> 9580), there can always be issue like we have here now or later
+ for kernels of a more recent version. While this package is to enable
+ people running legacy kernels to be able to enjoy their new toys, new
+ hardware support and bug fixes shall be backported as long as needed to
+ justify its name "backport-iwlwifi-dkms" here.
+
+ ========== original bug report ==========
+
Since backport-iwlwifi version 9241[1], a new module iwlmei was
introduced but not yet included in the dkms.conf installed. This fails
the kernel module loading with:
- iwlwifi: Unknown symbol iwl_mei_is_connected (err -2)
+ iwlwifi: Unknown symbol iwl_mei_is_connected (err -2)
