When loading the module, I get : iwm0: mem 0xdcd00000-0xdcd01fff at device 0.0 on pci2 iwm0: hw rev 0x200, fw ver 16.242414.0, address e4:b3:18:fb:f3:6a wlan0: Ethernet address: e4:b3:18:fb:f3:6a iwm0: iwm_post_alive: sched addr mismatch: alive: 0x817080 prph: 0x800000 iwm0: dumping device error log iwm0: Start Error Log Dump: [dump available on request] iwm0: iwm_intr: controller panicked, iv_state = 0; restarting wlan0: ieee80211_new_state_locked: pending INIT -> SCAN transition lost iwm0: failed to send bt coex configuration: 35 iwm_run_init_mvm_ucode: failed 35 iwm_init_hw failed 35 in a loop. Reverting that particular revision fixes the issue for me. I'm of course willing to act as a guinea pig, please let me know if you need me to test anything. Regards, Olivier
