I have switched now to my T540p with a 7260AC wifi chip. When I load iwm during boot, the computer crashes and enters a boot loop until I disable iwm at the loader prompt. I can then load it manually after boot and have wifi for some time. But it is pretty laggy and reconnects every 5 minutes or so with the following dmesg entry. ------ dmesg ------ wlan0: link state changed to DOWN wlan0: ieee80211_new_state_locked: pending SCAN -> ASSOC transition lost iwm0: iwm_update_edca: called iwm0: dumping device error log iwm0: Start Error Log Dump: iwm0: Status: 0x3, count: 6 iwm0: 0x00000086 | NMI_INTERRUPT_INST_ACTION_PT iwm0: 000002F0 | trm_hw_status0 iwm0: 00000000 | trm_hw_status1 iwm0: 00000B2C | branchlink2 iwm0: 00016A90 | interruptlink1 iwm0: 00015A28 | interruptlink2 iwm0: 00000000 | data1 iwm0: 00000004 | data2 iwm0: 07030000 | data3 iwm0: 00307A6F | beacon time iwm0: 000F858F | tsf low iwm0: 00000000 | tsf hi iwm0: 00000000 | time gp1 iwm0: 000F8590 | time gp2 iwm0: 00000000 | uCode revision type iwm0: 00000010 | uCode version major iwm0: 0003B2EE | uCode version minor iwm0: 00000144 | hw version iwm0: 00009004 | board version iwm0: 0000001C | hcmd iwm0: 00022088 | isr0 iwm0: 00800000 | isr1 iwm0: 00000002 | isr2 iwm0: 004034C1 | isr3 iwm0: 00000000 | isr4 iwm0: 01010112 | last cmd Id iwm0: 00000000 | wait_event iwm0: 000000A0 | l2p_control iwm0: 00000000 | l2p_duration iwm0: 00000000 | l2p_mhvalid iwm0: 00000000 | l2p_addr_match iwm0: 00000007 | lmpm_pmg_sel iwm0: 22121936 | timestamp iwm0: 00342028 | flow_handler iwm0: driver status: iwm0: tx ring 0: qid=0 cur=2 queued=2 iwm0: tx ring 1: qid=1 cur=0 queued=0 iwm0: tx ring 2: qid=2 cur=0 queued=0 iwm0: tx ring 3: qid=3 cur=0 queued=0 iwm0: tx ring 4: qid=4 cur=0 queued=0 iwm0: tx ring 5: qid=5 cur=0 queued=0 iwm0: tx ring 6: qid=6 cur=0 queued=0 iwm0: tx ring 7: qid=7 cur=0 queued=0 iwm0: tx ring 8: qid=8 cur=0 queued=0 iwm0: tx ring 9: qid=9 cur=34 queued=0 iwm0: tx ring 10: qid=10 cur=0 queued=0 iwm0: tx ring 11: qid=11 cur=0 queued=0 iwm0: tx ring 12: qid=12 cur=0 queued=0 iwm0: tx ring 13: qid=13 cur=0 queued=0 iwm0: tx ring 14: qid=14 cur=0 queued=0 iwm0: tx ring 15: qid=15 cur=0 queued=0 iwm0: tx ring 16: qid=16 cur=0 queued=0 iwm0: tx ring 17: qid=17 cur=0 queued=0 iwm0: tx ring 18: qid=18 cur=0 queued=0 iwm0: tx ring 19: qid=19 cur=0 queued=0 iwm0: tx ring 20: qid=20 cur=0 queued=0 iwm0: tx ring 21: qid=21 cur=0 queued=0 iwm0: tx ring 22: qid=22 cur=0 queued=0 iwm0: tx ring 23: qid=23 cur=0 queued=0 iwm0: tx ring 24: qid=24 cur=0 queued=0 iwm0: tx ring 25: qid=25 cur=0 queued=0 iwm0: tx ring 26: qid=26 cur=0 queued=0 iwm0: tx ring 27: qid=27 cur=0 queued=0 iwm0: tx ring 28: qid=28 cur=0 queued=0 iwm0: tx ring 29: qid=29 cur=0 queued=0 iwm0: tx ring 30: qid=30 cur=0 queued=0 iwm0: rx ring: cur=34 iwm0: 802.11 state 1 iwm0: iwm_intr: controller panicked, iv_state = 1; restarting wlan0: ieee80211_new_state_locked: pending SCAN -> AUTH transition lost iwm0: PHY ctxt cmd error. ret=35 iwm0: iwm_auth: failed add phy ctxt! iwm0: iwm_newstate: could not move to auth state: 60 iwm0: iwm_update_edca: called iwm0: iwm_update_edca: called iwm0: iwm_update_edca: called wlan0: link state changed to UP ------ end dmesg ------ Cheers, Stefan
