And shortly after I wrote that, while associating while getting an IP with dhclient when associating with a WPA encrypted AP, I got this backtrace in my logs: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready ADDRCONF(NETDEV_UP): eth0: link is not ready 0000:00:19.0: eth0: Link is Up 10 Mbps Full Duplex, Flow Control: None 0000:00:19.0: eth0: 10/100 speed: disabling TSO ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready martian source 255.255.255.255 from 134.184.26.55, on dev eth0 ll header: ff:ff:ff:ff:ff:ff:00:16:cb:06:4b:54:08:00 wlan0: disassociating by local choice (reason=3) wlan0: no IPv6 routers present wlan0: authenticate with AP 00:0d:54:a0:07:e3 wlan0: authenticate with AP 00:0d:54:a0:07:e3 wlan0: authenticated wlan0: associate with AP 00:0d:54:a0:07:e3 wlan0: RX ReassocResp from 00:0d:54:a0:07:e3 (capab=0x431 status=0 aid=7) wlan0: associated eth0: no IPv6 routers present iwlagn: index 255 not used in uCode key table. iwlagn 0000:0c:00.0: PCI INT A disabled iwlagn 0000:0c:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 iwlagn 0000:0c:00.0: restoring config space at offset 0x1 (was 0x100102, writing 0x100106) general protection fault: 0000 [1] SMP CPU 1 Modules linked in: sit tunnel4 i915 drm af_packet ipt_MASQUERADE iptable_nat nf_nat hidp nf_conntrack_ipv4 xt_state nf_conntrack ipt_REJECT bnep xt_tcpudp btusb iptable_filter ip_tables rfcomm x_tables bridge l2cap bluetooth stp ipv6 kvm_intel kvm vboxdrv binfmt_misc fuse nls_utf8 nls_cp437 vfat fat ext3 jbd loop cpufreq_ondemand cpufreq_conservative cpufreq_powersave acpi_cpufreq freq_table nvram i8k snd_hda_intel arc4 firewire_ohci ecb firewire_core snd_hwdep crc_itu_t snd_seq_dummy crypto_blkcipher snd_seq_oss thermal snd_seq_midi_event i2c_i801 pcmcia video wmi snd_seq i2c_core ac button battery processor sg snd_seq_device iwlagn snd_pcm_oss sr_mod snd_pcm iwlcore usbhid sdhci_pci ohci1394 ricoh_mmc sdhci ieee1394 rfkill led_class snd_timer output e1000e snd_page_alloc mmc_core yenta_socket rsrc_nonstatic pcmcia_core snd_mixer_oss rtc_cmos joydev dcdbas snd mac80211 soundcore ff_memless cfg80211 evdev dm_snapshot dm_zero dm_mirror dm_log dm_mod ata_piix ahci libata dock sd_mod scsi_mod crc_t10dif xfs uhci_hcd ohci_hcd ehci_hcd usbcore [last unloaded: scsi_wait_scan] Pid: 29422, comm: ifconfig Not tainted 2.6.27-tmb-desktop-2mdv #1 RIP: 0010:[<ffffffffa027b25b>] [<ffffffffa027b25b>] iwl_eeprom_query16 +0xb/0x20 [iwlcore] RSP: 0018:ffff8800b193fb48 EFLAGS: 00010002 RAX: 7fff88011a87b800 RBX: 0000000000000286 RCX: 00000000800c00f0 RDX: ffffc200050b403c RSI: 0000000000000090 RDI: ffff88011a0c1900 RBP: ffff8800b193fb48 R08: 0000000000000001 R09: ffff8800b193fb1c R10: 0000000000000000 R11: 0000000000000000 R12: ffff88011a0c1900 R13: ffff88011a0c1900 R14: ffff88011a0c2348 R15: 0000000000000282 FS: 00007f75811606f0(0000) GS:ffff88011fc02980(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 00000000016df108 CR3: 000000007c005000 CR4: 00000000000026e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process ifconfig (pid: 29422, threadinfo ffff8800b193e000, task ffff8800bbccd700) Stack: ffff8800b193fb98 ffffffffa02c81fb 0000000000000282 ffffffffffffff04 42ffffff804dd893 0000000000000286 ffff88011a0c1900 ffff88011a0c2348 ffff88011a0c2a50 ffff88011a0c2350 ffff8800b193fbc8 ffffffffa0279a66 Call Trace: [<ffffffffa02c81fb>] iwl5000_nic_config+0x6b/0x200 [iwlagn] [<ffffffffa0279a66>] iwl_hw_nic_init+0x96/0x160 [iwlcore] [<ffffffffa02be795>] __iwl4965_up+0xb5/0x2d0 [iwlagn] [<ffffffffa02bf1c8>] iwl4965_mac_start+0x408/0x710 [iwlagn] [<ffffffff8046efe3>] ?
