Unfortunately after the resume event I loose access to the network. As far as the system is concerned the network is configured properly but every attempt to ping local nodes fails with "Host not reachable". If also seen an oops or two but I don't know id that is related: [ 289.816066] ------------[ cut here ]------------ [ 289.816077] WARNING: at net/sched/sch_generic.c:246 dev_watchdog+0x132/0x1da() [ 289.816080] Hardware name: System Product Name [ 289.816083] NETDEV WATCHDOG: eth0 (r8169): transmit queue 0 timed out [ 289.816085] Modules linked in: nls_iso8859_1 nls_cp437 vfat fat joydev usb_storage usbhid usb_libusual bridge stp llc bnep rfcomm l2cap bluetooth ipv6 snd_pcm_oss snd_mixer_oss snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device kvm_intel kvm acpi_cpufreq snd_hda_codec_analog uhci_hcd usbcore snd_hda_intel snd_hda_codec firewire_ohci snd_hwdep snd_pcm snd_timer snd firewire_core crc_itu_t soundcore snd_page_alloc ide_cd_mod pcspkr evdev cdrom thermal processor nls_base unix [last unloaded: ehci_hcd] [ 289.816135] Pid: 0, comm: swapper Not tainted 2.6.31-rc9-ajb-00012-g3ff323f-dirty #84 [ 289.816138] Call Trace: [ 289.816140] [] ? dev_watchdog+0x132/0x1da [ 289.816152] [] warn_slowpath_common+0x7c/0xa9 [ 289.816157] [] warn_slowpath_fmt+0x69/0x6b [ 289.816165] [] ? uhci_scan_schedule+0x194/0x86a [uhci_hcd] [ 289.816169] [] ? lock_timer_base+0x2b/0x4f [ 289.816174] [] ? mod_timer+0x111/0x123 [ 289.816180] [] ? uhci_hub_status_data+0x16e/0x17d [uhci_hcd] [ 289.816185] [] ? netdev_drivername+0x48/0x4f [ 289.816189] [] dev_watchdog+0x132/0x1da [ 289.816211] [] ? usb_hcd_poll_rh_status+0x144/0x153 [usbcore] [ 289.816215] [] ? dev_watchdog+0x0/0x1da [ 289.816220] [] run_timer_softirq+0x198/0x20d [ 289.816226] [] ? lapic_next_event+0x1d/0x21 [ 289.816231] [] __do_softirq+0xd6/0x19a [ 289.816235] [] call_softirq+0x1c/0x28 [ 289.816239] [] do_softirq+0x39/0x77 [ 289.816243] [] irq_exit+0x44/0x7e [ 289.816248] [] smp_apic_timer_interrupt+0x8d/0x9b [ 289.816253] [] apic_timer_interrupt+0x13/0x20 [ 289.816256] [] ? mwait_idle+0xb9/0xf0 [ 289.816264] [] ? atomic_notifier_call_chain+0x13/0x15 [ 289.816268] [] ? cpu_idle+0x57/0x98 [ 289.816273] [] ? rest_init+0x66/0x68 [ 289.816278] [] ? start_kernel+0x343/0x34e [ 289.816283] [] ? x86_64_start_reservations+0xaa/0xae [ 289.816287] [] ? x86_64_start_kernel+0xe1/0xe8 [ 289.816290] ---[ end trace 01c3a2a7a5f34536 ]--- [ 290.635368] r8169: eth0: link up [ 314.635844] r8169: eth0: link up I'm currently running 2.6.31-rc9-ajb-00012-g3ff323f-dirty and am willing to test any patches that might be going.
