Message-ID: <4FD4F28B.4070003@palosanto.com> Date: Sun, 10 Jun 2012 14:16:27 -0500 From: Alex VillacĂs Lasso <a_villacis@...osanto.com> To: netdev@...r.kernel.org Subject: REGRESSION: 3.4.0->3.5.0-rc2 kernel WARNING on cable plug on Acer Aspire One, no network System is an Acer Aspire One ZG5 running Fedora 16 32-bits with latest updates. I compiled and ran linux-3.4.0 with no issues. I then compiled 3.5.0-rc2 with the attached kernel config, and rebooted with unplugged ethernet cable. I started an ordinary user session and then plugged the ethernet cable. Almost immediately I got a kernel BUG with the following backtrace, and the DHCP failed, as well as any other network communication: [ 261.818521] r8169 0000:02:00.0: p1p1: link up [ 261.819603] IPv6: ADDRCONF(NETDEV_CHANGE): p1p1: link becomes ready [ 273.712065] ------------[ cut here ]------------ [ 273.712096] WARNING: at net/sched/sch_generic.c:255 dev_watchdog+0x1f2/0x200() [ 273.712105] Hardware name: AOA150 [ 273.712113] NETDEV WATCHDOG: p1p1 (r8169): transmit queue 0 timed out [ 273.712342] Modules linked in: fuse be2iscsi iscsi_boot_sysfs bnx2i cnic uio cxgb4i cxgb4 cxgb3i libcxgbi cxgb3 mdio ib_iser rdma_cm ib_cm iw_cm ib_sa ib_mad ib_core ib_addr iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi fcoe libfcoe libfc scsi_transport_fc scsi_tgt 8021q garp stp llc nf_conntrack_ipv4 nf_defrag_ipv4 ip6t_REJECT nf_conntrack_ipv6 nf_defrag_ipv6 xt_state nf_conntrack ip6table_filter ip6_tables snd_hda_codec_realtek snd_hda_intel snd_hda_codec snd_hwdep snd_seq snd_seq_device arc4 snd_pcm snd_timer ath5k ath mac80211 coretemp cfg80211 sparse_keymap rfkill uvcvideo videobuf2_core videodev media videobuf2_vmalloc videobuf2_memops snd soundcore snd_page_alloc wmi acerhdf lpc_ich joydev pcspkr r8169 i2c_i801 microcode mii serio_raw uinput i915 drm_kms_helper drm i2c_algo_bit i2c_core video [last unloaded: scsi_wait_scan] [ 273.712358] Pid: 0, comm: swapper/0 Not tainted 3.5.0-rc2 #3 [ 273.712365] Call Trace: [ 273.712386] [<c04399c2>] warn_slowpath_common+0x72/0xa0 [ 273.712402] [<c08782c2>] ? dev_watchdog+0x1f2/0x200 [ 273.712416] [<c08782c2>] ? dev_watchdog+0x1f2/0x200 [ 273.712430] [<c0439a93>] warn_slowpath_fmt+0x33/0x40 [ 273.712445] [<c08782c2>] dev_watchdog+0x1f2/0x200 [ 273.712474] [<c0447e0f>] run_timer_softirq+0xef/0x360 [ 273.712489] [<c047200d>] ? rebalance_domains+0x13d/0x160 [ 273.712505] [<c08780d0>] ? pfifo_fast_dequeue+0xe0/0xe0 [ 273.712519] [<c047206d>] ? run_rebalance_domains+0x3d/0x110 [ 273.712535] [<c04411c0>] ? local_bh_enable_ip+0xa0/0xa0 [ 273.712548] [<c0441249>] __do_softirq+0x89/0x210 [ 273.712564] [<c04411c0>] ? local_bh_enable_ip+0xa0/0xa0 [ 273.712583] <IRQ> [<c0441686>] ? irq_exit+0x86/0xb0 [ 273.712597] [<c0404b9b>] ? do_IRQ+0x4b/0xb0 [ 273.712613] [<c048bea9>] ? tick_program_event+0x29/0x30 [ 273.712630] [<c0959830>] ? common_interrupt+0x30/0x38 [ 273.712646] [<c044007b>] ? jiffies_64_to_clock_t+0x2b/0x60 [ 273.712662] [<c06b6333>] ? intel_idle+0xc3/0x120 [ 273.712679] [<c081e865>] ? cpuidle_enter+0x15/0x20 [ 273.712694] [<c081edec>] ? cpuidle_idle_call+0x9c/0x320 [ 273.712708] [<c040b48a>] ? cpu_idle+0xaa/0x100 [ 273.712724] [<c09324b4>] ? rest_init+0x6c/0x78 [ 273.712741] [<c0bf19b8>] ? start_kernel+0x365/0x36b [ 273.712755] [<c0bf148e>] ? repair_env_string+0x51/0x51 [ 273.712770] [<c0bf12c2>] ? i386_start_kernel+0x78/0x7d [ 273.712779] ---[ end trace 64b107363f32cf24 ]--- [ 273.716256] r8169 0000:02:00.0: p1p1: link up [ 279.717247] r8169 0000:02:00.0: p1p1: link up [ 285.717279] r8169 0000:02:00.0: p1p1: link up View attachment "config-3.5.0-rc2" of type "text/plain" (129517 bytes) View attachment "dmesg-3.4.0.txt" of type "text/plain" (58807 bytes) View attachment "dmesg-3.5.0-rc2.txt" of type "text/plain" (68511 bytes) View attachment "lspci-3.4.0.txt" of type "text/plain" (28601 bytes) View attachment "lspci-3.5.0-rc2.txt" of type "text/plain" (28600 bytes) View attachment "messages.3.4.0.txt" of type "text/plain" (118015 bytes) View attachment "messages.3.5.0-rc2.txt" of type "text/plain" (160641 bytes) View attachment "proc-interrupts.3.4.0.txt" of type "text/plain" (1504 bytes) View attachment "proc-interrupts.3.5.0-rc2.txt" of type "text/plain" (1505 bytes)
