Arch Linux

Description:
Intel AC 7260 is a standard wireless adapter employed by multiple laptops. In arch kernel 5.18.16, this device is driven by iwlwifi kernel module. Given the mobility of laptops, it's not a rare case when one needs to connect to an 802.11 network deployed with multiple access points(APs), which usually comes with wap-enterprise. Most network engineering who design and deploy the enterprise 802.11 network don't intentionally avoid the emergence of overlapped regions between APs, as a particular device named access controller(AC) would handle the client-AP association relations in the overlapped areas. Therefore, given the signal strength fluctuation and the load condition of a particular AP, the AC might disassociate a specific client and appoint a new AP to associate. Therefore, a laptop with multiple AP in reach could periodically suffer from the reassociation process without movement. However, moving from one AP to another may artificially trigger a reassociation.
When the reassociation happens, iwlwifi crashes, and the kernel captures the error log. There is a current workaround without rebooting, which removes the adapter via /sys/class/pci_bus/0000:0X/device/remove, removes the iwlwifi related modules via modprob -r and then rescan the PCI devices via /sys/bus/pci/rescan. However, iwlwifi would crash next time when reassociation happens.

Additional info:
* package version(s): linux 5.18.16.arch1-1
* config: iwlwifi.conf
* log file: iwlwifi.dmesg

Steps to reproduce:
0. Borrow a ThinkPad T440 with FRU capable Intel AC-7260 wireless adapter
1. Use NetworkManager to connect to a WPA-Enterprise 802.11 network with multiple APs
2. With the laptop in hand, gently walk from one AP to another.
3. If nothing abnormal in dmesg, keep walking between multiple APs.
