Description of problem: The affected system suddenly became unresponsive over the network. Two concurrent DVB-T recordings were running and I was copying some large file to a Samba share on this system. For some minutes I couldn't access the Samba share anymore and my SSH session was also dropped. After some minutes the system became responsive again over the network (SSH and Samba) and I found this in /var/log/messages: Nov 26 20:23:01 beverly kernel: ------------[ cut here ]------------ Nov 26 20:23:01 beverly kernel: WARNING: at net/sched/sch_generic.c:246 dev_watchdog+0xf3/0x164() (Not tainted) Nov 26 20:23:01 beverly kernel: Hardware name: MS-7514 Nov 26 20:23:01 beverly kernel: NETDEV WATCHDOG: eth0 (r8169): transmit queue 0 timed out Nov 26 20:23:01 beverly kernel: Modules linked in: fuse mt2060 dvb_usb_dib0700 dib7000p dib7000m dvb_usb dib3000mc dibx000_common dib0070 nfs fscache nfsd lockd nfs_acl auth_rpcgss exportfs sunrpc ipv6 cpufreq_ondemand acpi_cpufreq freq_table dm_multipath uinput dvb_pll cx22702 cx88_dvb snd_hda_codec_atihdmi cx88_vp3054_i2c snd_hda_codec_realtek videobuf_dvb dvb_core snd_hda_intel snd_hda_codec snd_hwdep snd_seq snd_seq_device cx8800 cx8802 cx88xx snd_pcm ir_common v4l2_common videodev v4l1_compat tveeprom v4l2_compat_ioctl32 btcx_risc videobuf_dma_sg r8169 videobuf_core mii iTCO_wdt iTCO_vendor_support ppdev i2c_i801 snd_timer snd soundcore snd_page_alloc parport_pc parport raid456 raid6_pq async_xor async_memcpy async_tx xor raid1 radeon ttm drm_kms_helper drm i2c_algo_bit i2c_core [last unloaded: microcode] Nov 26 20:23:01 beverly kernel: Pid: 0, comm: swapper Not tainted 2.6.31.5-127.fc12.x86_64 #1 Nov 26 20:23:01 beverly kernel: Call Trace: Nov 26 20:23:01 beverly kernel: <IRQ> [<ffffffff81051694>] warn_slowpath_common+0x84/0x9c Nov 26 20:23:01 beverly kernel: [<ffffffff81051703>] warn_slowpath_fmt+0x41/0x43 Nov 26 20:23:01 beverly kernel: [<ffffffff8138e561>] ? netif_tx_lock+0x44/0x6d Nov 26 20:23:01 beverly kernel: [<ffffffff8138e6cb>] dev_watchdog+0xf3/0x164 Nov 26 20:23:01 beverly kernel: [<ffffffff8106eb1f>] ? getnstimeofday+0x5b/0xaf Nov 26 20:23:01 beverly kernel: [<ffffffff81064008>] ? __queue_work+0x3a/0x43 Nov 26 20:23:01 beverly kernel: [<ffffffff8106c546>] ? sched_clock_cpu+0x16e/0x176 Nov 26 20:23:01 beverly kernel: [<ffffffff8105be64>] run_timer_softirq+0x19f/0x21c Nov 26 20:23:01 beverly kernel: [<ffffffff8106e897>] ? clocksource_read+0xf/0x11 Nov 26 20:23:01 beverly kernel: [<ffffffff810256aa>] ? apic_write+0x16/0x18 Nov 26 20:23:01 beverly kernel: [<ffffffff810575b4>] __do_softirq+0xdd/0x1ad Nov 26 20:23:01 beverly kernel: [<ffffffff81012eac>] call_softirq+0x1c/0x30 Nov 26 20:23:01 beverly kernel: [<ffffffff810143fb>] do_softirq+0x47/0x8d Nov 26 20:23:01 beverly kernel: [<ffffffff810572c6>] irq_exit+0x44/0x86 Nov 26 20:23:01 beverly kernel: [<ffffffff8141eab2>] smp_apic_timer_interrupt+0x86/0x94 Nov 26 20:23:01 beverly kernel: [<ffffffff81012873>] apic_timer_interrupt+0x13/0x20 Nov 26 20:23:01 beverly kernel: <EOI> [<ffffffff8101907f>] ? mwait_idle+0x91/0xae Nov 26 20:23:01 beverly kernel: [<ffffffff8101907f>] ? mwait_idle+0x91/0xae Nov 26 20:23:01 beverly kernel: [<ffffffff81019021>] ? mwait_idle+0x33/0xae Nov 26 20:23:01 beverly kernel: [<ffffffff8141d079>] ? atomic_notifier_call_chain+0x13/0x15 Nov 26 20:23:01 beverly kernel: [<ffffffff81010bb8>] ? enter_idle+0x25/0x27 Nov 26 20:23:01 beverly kernel: [<ffffffff81010c60>] ? cpu_idle+0xa6/0xe9 Nov 26 20:23:01 beverly kernel: [<ffffffff814145be>] ? start_secondary+0x1f3/0x234 Nov 26 20:23:01 beverly kernel: ---[ end trace fdd61f0e1b4eb08f ]--- Version-Release number of selected component (if applicable): 2.6.31.5-127.fc12.x86_64 How reproducible: Steps to Reproduce: 1. 2. 3.

This is probably the same issue as with bug #620047 for the current F13 kernel. I'll close this as a duplicate. *** This bug has been marked as a duplicate of bug 620047 ***
