I personally do not recommend a BIOS upgrade for this kind of bug. It is risky and won't add much value. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1445775 Title: RTL8723BE throws stack trace in kernel 3.19 and disconnects To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1445775/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sayantan Das, thank you for reporting this and helping make Ubuntu better. The stacktrace you posted is graphics related, versus network. However, graphics crashes can be quite ugly in the collateral issues that result from them. Despite this, as per http://support.lenovo.com/us/en/products/laptops- and-netbooks/flex-series/flex-2-14-notebook-lenovo an update to your computer's buggy and outdated BIOS is available (A0CN35WW). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, and the information above is provided, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags removed: bios-outdated-a3cn32ww ** Tags added: bios-outdated-a0cn35ww ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1445775 Title: RTL8723BE throws stack trace in kernel 3.19 and disconnects To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1445775/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

apport information ** Tags added: apport-collected vivid ** Description changed: Hi, I have the well known, problem causing, RTL8723BE wifi card on Lenovo Flex 2 laptop and I'm running Ubuntu 15.04 beta. If there is too much traffic through the wifi card like downloading an iso via torrent , I get a stacktrace and the wifi disconnects and does not connect automatically. Either I have to disable the wifi and re-enable it or I have to restart my laptop to get the wifi connection back. the stack trace is below Apr 18 18:16:23 flex2 kernel: [ cut here ] Apr 18 18:16:23 flex2 kernel: WARNING: CPU: 0 PID: 0 at /build/buildd/linux-3.19.0/drivers/gpu/drm/i915/intel_display.c:9713 intel_check_page_flip+0xda/0xf0 [i915]() Apr 18 18:16:23 flex2 kernel: Kicking stuck page flip: queued at 169616, now 169621 Apr 18 18:16:23 flex2 kernel: Modules linked in: uas usb_storage vmw_vsock_vmci_transport vsock vmw_vmci pci_stub vboxpci(OE) vboxnetadp(OE) vboxnetflt(OE) vboxdrv(OE) ctr ccm rfcomm bnep thinkpad_acpi binfmt_misc nvram msr nls_iso8859_1 intel_rapl iosf_mbi x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel kvm crct10dif_pclmul snd_soc_rt5640 crc32_pclmul snd_soc_rl6231 ghash_clmulni_intel uvcvideo videobuf2_vmalloc videobuf2_memops aesni_intel snd_soc_core snd_hda_codec_realtek snd_hda_codec_hdmi snd_compress snd_hda_codec_generic snd_hda_intel snd_hda_controller snd_hda_codec snd_pcm_dmaengine hid_multitouch aes_x86_64 snd_hwdep arc4 videobuf2_core snd_pcm v4l2_common rtl8723be btusb btcoexist rtl8723_common lrw rtl_pci nouveau rtlwifi mac80211 i915 bluetooth cfg80211 gf128mul snd_seq_midi glue_helper mxm_wmi Apr 18 18:16:23 flex2 kernel: videodev snd_seq_midi_event ablk_helper media ttm snd_rawmidi cryptd joydev snd_seq dm_multipath snd_seq_device scsi_dh drm_kms_helper mei_me snd_timer dw_dmac ideapad_laptop drm snd mei sparse_keymap shpchp lpc_ich i2c_hid snd_soc_sst_acpi i2c_algo_bit i2c_designware_platform video soundcore dw_dmac_core 8250_dw i2c_designware_core spi_pxa2xx_platform mac_hid serio_raw wmi ip6t_REJECT nf_reject_ipv6 nf_log_ipv6 xt_hl ip6t_rt nf_conntrack_ipv6 nf_defrag_ipv6 ipt_REJECT nf_reject_ipv4 nf_log_ipv4 nf_log_common xt_LOG xt_limit xt_tcpudp xt_addrtype nf_conntrack_ipv4 nf_defrag_ipv4 xt_conntrack ip6table_filter ip6_tables nf_conntrack_netbios_ns nf_conntrack_broadcast nf_nat_ftp nf_nat nf_conntrack_ftp nf_conntrack iptable_filter ip_tables sunrpc x_tables parport_pc ppdev lp parport autofs4 Apr 18 18:16:23 flex2 kernel: usbhid hid psmouse ahci libahci r8169 mii dm_mirror dm_region_hash dm_log sdhci_acpi sdhci Apr 18 18:16:23 flex2 kernel: CPU: 0 PID: 0 Comm: swapper/0 Tainted: G W OE 3.19.0-12-generic #12-Ubuntu Apr 18 18:16:23 flex2 kernel: Hardware name: LENOVO 20404/Lenovo Flex 2-14, BIOS A0CN21WW 03/21/2014 Apr 18 18:16:23 flex2 kernel: c0748e10 88012f203d28 817c2175 0007 Apr 18 18:16:23 flex2 kernel: 88012f203d78 88012f203d68 8107595a 88012f203d88 Apr 18 18:16:23 flex2 kernel: 88012a898000 8800bf12a000 8800bf12a1a8 Apr 18 18:16:23 flex2 kernel: Call Trace: Apr 18 18:16:23 flex2 kernel:[] dump_stack+0x45/0x57 Apr 18 18:16:23 flex2 kernel: [] warn_slowpath_common+0x8a/0xc0 Apr 18 18:16:23 flex2 kernel: [] warn_slowpath_fmt+0x46/0x50 Apr 18 18:16:23 flex2 kernel: [] intel_check_page_flip+0xda/0xf0 [i915] Apr 18 18:16:23 flex2 kernel: [] ironlake_irq_handler+0x2e8/0xfd0 [i915] Apr 18 18:16:23 flex2 kernel: [] ? rebalance_domains+0x16f/0x280 Apr 18 18:16:23 flex2 kernel: [] ? __note_gp_changes+0x20/0x60 Apr 18 18:16:23 flex2 kernel: [] handle_irq_event_percpu+0x77/0x1a0 Apr 18 18:16:23 flex2 kernel: [] handle_irq_event+0x41/0x70 Apr 18 18:16:23 flex2 kernel: [] handle_edge_irq+0x6e/0x120 Apr 18 18:16:23 flex2 kernel: [] handle_irq+0x22/0x40 Apr 18 18:16:23 flex2 kernel: [] do_IRQ+0x4f/0xf0 Apr 18 18:16:23 flex2 kernel: [] common_interrupt+0x6d/0x6d Apr 18 18:16:23 flex2 kernel:[] ? cpuidle_enter_state+0x65/0x160 Apr 18 18:16:23 flex2 kernel: [] ? cpuidle_enter_state+0x51/0x160 Apr 18 18:16:23 flex2 kernel: [] cpuidle_enter+0x17/0x20 Apr 18 18:16:23 flex2 kernel: [] cpu_startup_entry+0x311/0x3b0 Apr 18 18:16:23 flex2 kernel: [] rest_init+0x77/0x80 Apr 18 18:16:23 flex2 kernel: [] start_kernel+0x482/0x48f Apr 18 18:16:23 flex2 kernel: [] ? early_idt_handlers+0x120/0x120 Apr 18 18:16:23 flex2 kernel: [] x86_64_start_reservations+0x2a/0x2c Apr 18 18:16:23 flex2 kernel: [] x86_64_start_kernel+0x143/0x152 Apr 18 18:16:23 flex2 kernel: ---[ end trace 78327f32f7248597 ]--- + --- + ApportVersion: 2.17.2-0ubuntu1 + Architecture: amd64 + AudioDevicesInUse: + USERPID ACCESS COMMAND + /dev/snd/controlC1: sayantan 2080 F pulseaudio + /dev/snd/controlC0: sayantan 2080 F pulseaudio +
