Hello, Anyone who can tell me whether I should worry about the kernel warning shown below ? I've observed that warning for the first time with 3.1-rc5 and hadn't seen it yet with 3.1-rc4 or any older kernel. ------------[ cut here ]------------ WARNING: at net/sched/sch_generic.c:255 dev_watchdog+0x24f/0x260() Hardware name: P5Q DELUXE NETDEV WATCHDOG: eth0 (skge): transmit queue 0 timed out Modules linked in: snd_pcm_oss snd_mixer_oss snd_seq snd_seq_device af_packet rdma_ucm rdma_cm iw_cm ib_addr ib_ipoib ib_cm ib_sa ib_uverbs ib_umad mlx4_ib ib_mad ib_core microcode cpufreq_conservative cpufreq_userspaceq mperf dm_mod snd_hda_codec_hdmi snd_hda_codec_analog snd_hda_intel snd_hda_codec snd_hwdep snd_pcm snd_timer snd sr_mod mlx4_core sg cdrom soundcore i2c_i801 snd_page_alloc i2c_core pcspkr button uhci_hcd ehci_hcd sxt3 mbcache jbd fan ata_generic ata_piix pata_marvell ahci libahci libata scsi_mod thermal processor thermal_sys hwmon Pid: 6260, comm: wish Not tainted 3.1.0-rc4-scst-debug+ #2 Call Trace: <IRQ> [<ffffffff8104564f>] warn_slowpath_common+0x7f/0xc0 [<ffffffff81045746>] warn_slowpath_fmt+0x46/0x50 [<ffffffff813268df>] dev_watchdog+0x24f/0x260 [<ffffffff8105602a>] run_timer_softirq+0x19a/0x3f0 [<ffffffff81055f97>] ? run_timer_softirq+0x107/0x3f0 [<ffffffff81326690>] ? pfifo_fast_init+0xa0/0xa0 [<ffffffff8104cecd>] __do_softirq+0xcd/0x250 [<ffffffff813e5cec>] call_softirq+0x1c/0x30 [<ffffffff810043bd>] do_softirq+0x8d/0xc0 [<ffffffff8104d36e>] irq_exit+0xae/0xe0 [<ffffffff813e637e>] smp_apic_timer_interrupt+0x6e/0x99 [<ffffffff813e4570>] apic_timer_interrupt+0x70/0x80 <EOI> [<ffffffff813dbe0a>] ? retint_swapgs+0xe/0x13 ---[ end trace fbbed52d2a66b808 ]--- Bart.
