There are some public bug reports on bugzilla, but none of them look similar to ours.
https://bugzilla.kernel.org/show_bug.cgi?id=205749 It claims the fix lands on v5.4.16 and v5.5, and this patch already has been included in our focal kernel. It doesn't work for us. https://bugzilla.kernel.org/show_bug.cgi?id=206329 This one is still open, and doesn't get fixed at v5.6-rc3, so not the same as ours. https://bugzilla.kernel.org/show_bug.cgi?id=206719 The error message pretty similar to ours and fails at v5.4.22, but no one follow up https://bugzilla.kernel.org/show_bug.cgi?id=206661 Another regression after v5.6-rc1, no fix until v5.6-rc4, affects our linux-5.6 oem kernel. https://bugzilla.kernel.org/show_bug.cgi?id=206607 Similar errors, no follow up https://bugzilla.kernel.org/show_bug.cgi?id=206395 Similar errors, but doesn't verify it with latest v5.6 mainline kernel.

After bisect the kernel, the first bad commit is b3bd6416fc77 iwlwifi: assume the driver_data is a trans_cfg, but allow full cfg To avoid conflicts, we have to backport the following commits from mainline kernel b81b7bd02eda iwlwifi: remove some outdated iwl22000 configurations c042f0c77f3d iwlwifi: allocate more receive buffers for HE devices 5661925a9b38 iwlwifi: pcie: rx: use rxq queue_size instead of constant bfc3e9fdbfb8 iwlwifi: 22000: fix some indentation 3681021fc6af iwlwifi: remove IWL_DEVICE_22560/IWL_DEVICE_FAMILY_22560 [Test] Verified on Dell XPS 9300 with Killer AX1650i wifi card and XPS 13 2-1 platform, wifi keeps working after reboot 10 times. [Regression Potential] Medium, the code changes a lot, although the test results are all positive, it's still hard to evaluate the regression potential.
