I also have a similar problem on Ubuntu 13.04 with latest kernel 3.8.0-19-generic. My problem can be considered as crital since when I enable broadcom proprietry wireless driver, ubuntu freezes on boot.
Below is the kernel log just before the freeze: May 1 23:38:38 Me-PC kernel: [ 218.077000] general protection fault: 0000 [#1] SMP May 1 23:38:38 Me-PC kernel: [ 218.077046] Modules linked in: parport_pc(F) ppdev(F) binfmt_misc(F) sctp(F) libcrc32c(F) lp(F) parport(F) bnep rfcomm snd_hda_codec_hdmi nvidia(POF) snd_hda_cod ec_conexant snd_hda_intel joydev(F) snd_hda_codec lib80211_crypt_tkip wl(POF) snd_hwdep(F) snd_pcm(F) snd_page_alloc(F) snd_seq_midi(F) snd_seq_midi_event(F) snd_rawmidi(F) snd_seq(F) uvcvideo c oretemp videobuf2_vmalloc videobuf2_memops videobuf2_core snd_seq_device(F) snd_timer(F) kvm_intel lib80211 ideapad_laptop wmi psmouse(F) videodev mei snd(F) cfg80211 mac_hid btusb lpc_ich kvm b luetooth serio_raw(F) sparse_keymap soundcore(F) ums_realtek usb_storage(F) microcode(F) ahci(F) libahci(F) video(F) r8169 May 1 23:38:38 Me-PC kernel: [ 218.077577] CPU 0 May 1 23:38:38 Me-PC kernel: [ 218.077590] Pid: 3484, comm: iwconfig Tainted: PF O 3.8.0-19-generic #29-Ubuntu LENOVO 20042 /Base Board Product Name May 1 23:38:38 Me-PC kernel: [ 218.077666] RIP: 0010:[<ffffffff8169b381>] [<ffffffff8169b381>] wireless_process_ioctl+0x91/0x1b0 May 1 23:38:38 Me-PC kernel: [ 218.077726] RSP: 0018:ffff880131f4fd80 EFLAGS: 00010282 May 1 23:38:38 Me-PC kernel: [ 218.077755] RAX: ffff880130d83000 RBX: 0000000000008b09 RCX: b218bbe08360afd9 May 1 23:38:38 Me-PC kernel: [ 218.077789] RDX: b218bbe08360afd9 RSI: ffff880131f4fe20 RDI: ffff880130d83000 May 1 23:38:38 Me-PC kernel: [ 218.077822] RBP: ffff880131f4fda8 R08: 0000000000000000 R09: ffffffff8169cb50 May 1 23:38:38 Me-PC kernel: [ 218.077855] R10: 0000000000000001 R11: 0000000000000246 R12: ffffffff8169cb50 May 1 23:38:38 Me-PC kernel: [ 218.077887] R13: ffffffff8169bec0 R14: ffff880131f4fdbc R15: ffff880131f4fe20 May 1 23:38:38 Me-PC kernel: [ 218.077919] FS: 00007f481854c740(0000) GS:ffff880137c00000(0000) knlGS:0000000000000000 May 1 23:38:38 Me-PC kernel: [ 218.077966] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 May 1 23:38:38 Me-PC kernel: [ 218.077993] CR2: 00007f4818148073 CR3: 0000000131f9e000 CR4: 00000000000007f0 May 1 23:38:38 Me-PC kernel: [ 218.078026] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 May 1 23:38:38 Me-PC kernel: [ 218.078058] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 May 1 23:38:38 Me-PC kernel: [ 218.078089] Process iwconfig (pid: 3484, threadinfo ffff880131f4e000, task ffff88012f851740) May 1 23:38:38 Me-PC kernel: [ 218.078142] Stack: May 1 23:38:38 Me-PC kernel: [ 218.078166] 0000000000000000 0000000000008b09 ffff880131f4fe20 ffffffff81cbb640 May 1 23:38:38 Me-PC kernel: [ 218.078235] 00007fff801d4130 ffff880131f4fde8 ffffffff8169c094 00008b0931f4fe40 May 1 23:38:38 Me-PC kernel: [ 218.078308] 0000000000008b09 00007fff801d4130 ffff880131f4fe20 00000000ffffffe7 May 1 23:38:38 Me-PC kernel: [ 218.078376] Call Trace: May 1 23:38:38 Me-PC kernel: [ 218.078404] [<ffffffff8169c094>] wext_handle_ioctl+0x74/0xd0 May 1 23:38:38 Me-PC kernel: [ 218.078441] [<ffffffff815cb85e>] dev_ioctl+0xce/0x5e0 May 1 23:38:38 Me-PC kernel: [ 218.078475] [<ffffffff815b0542>] sock_ioctl+0xf2/0x2b0 May 1 23:38:38 Me-PC kernel: [ 218.078508] [<ffffffff811a5919>] do_vfs_ioctl+0x99/0x570 May 1 23:38:38 Me-PC kernel: [ 218.078540] [<ffffffff8119591b>] ? alloc_file+0x2b/0xd0 May 1 23:38:38 Me-PC kernel: [ 218.078575] [<ffffffff816caece>] ? _raw_spin_lock+0xe/0x20 May 1 23:38:38 Me-PC kernel: [ 218.078605] [<ffffffff811a5e81>] sys_ioctl+0x91/0xb0 May 1 23:38:38 Me-PC kernel: [ 218.078638] [<ffffffff816cf17e>] ? do_page_fault+0xe/0x10 May 1 23:38:38 Me-PC kernel: [ 218.078671] [<ffffffff816d379d>] system_call_fastpath+0x1a/0x1f May 1 23:38:38 Me-PC kernel: [ 218.078703] Code: 02 00 00 48 8b 90 70 01 00 00 48 85 c9 0f 84 80 00 00 00 48 8b 09 48 85 c9 74 78 48 85 d2 48 8b 89 90 03 00 00 0f 84 bf 00 00 00 <0f> b7 72 08 8d 8b 00 75 ff ff 39 f1 72 51 0f b7 72 0a 8d 8b 20 May 1 23:38:38 Me-PC kernel: [ 218.079145] RIP [<ffffffff8169b381>] wireless_process_ioctl+0x91/0x1b0 May 1 23:38:38 Me-PC kernel: [ 218.079185] RSP <ffff880131f4fd80> May 1 23:38:38 Me-PC kernel: [ 218.079250] ---[ end trace 39debde0b8072a31 ]--- -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1169653 Title: Ubuntu 13.04 / 12.04 // Lenovo B590 MBX29GE/627429G // WLAN Broadcom BMC 43142 and ACPI Issues/Bugs // kernel-bug-exists-upstream To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1169653/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
