Even with the original kernel the problem happened only twice and then never again.
Let me make a timeline before I get confused (feel free to skip it): 2008-10-31 10:14, I install linux-image-2.6.27-7-generic to 2.6.27-7.15. 2008-10-31 10:28, I reboot into the new kernel 2008-10-31 10:51, I reboot again (with the 'profile' boot option). The boot takes a really long time, then crashes with a kernel panic (blinking capslock led). The panic is not captured in the system log files, and is not visible on screen due to usplash. It's not related to this bug, I think. 2008-10-31 10:53, I reboot again without the 'profile' option. The boot is successful. 2008-10-31 11:17, I suspend. 2008-10-31 14:05, I resume. 2008-10-31 20:04, I suspend. 2008-10-31 20:04, the errors start (5233 repetitions of 'e1000e mutext contention' on this day. The very first messages are rather strange, e.g. [e10lo7.290] ea047.0fc1f28]2k_rc8kb+0 /0t0g1x9ce i[ce3.y4]289h7?.o9r8=dt0rA.004o.u5 2vvoe_slot esonsipher snd_rawi a_core r after a while they become readable 2008-10-31 20:33, I resume and notice the errors. 2008-10-31 21:33, I suspend and resume, to see if the errors would go away. 2008-10-31 23:23, I shut down the machine 2008-11-01 09:00, I boot it up, notice both LEDs are on, notice no e1000e errors in dmesg 2008-11-01 13:27, I suspend 2008-11-01 13:27, the errors start 2008-11-01 16:11, I resume, the errors continue (349 repetitions of 'e1000e mutext contention') 2008-11-01 16:15, I rmmod e1000e to see if it helps (yes) 2008-11-01 16:40, I suspend 2008-11-02 07:45, I resume 2008-11-02 11:34, I suspend 2008-11-02 17:03, I resume 2008-11-02 21:36, I suspend 2008-11-02 21:39, I resume 2008-11-02 21:48, I suspend 2008-11-03 00:02, I resume 2008-11-03 00:09, I suspend 2008-11-03 08:02, I resume, and see a scary message Nov 3 08:02:04 platonas kernel: [49099.700050] ------------[ cut here ]------------ Nov 3 08:02:04 platonas kernel: [49099.700053] WARNING: at /build/buildd/linux-2.6.27/arch/x86/kernel/ipi.c:123 send_IPI_mask_bitmask+0x99/0xb0() Nov 3 08:02:04 platonas kernel: [49099.700055] Modules linked in: e1000e aes_i586 aes_generic ecryptfs isofs loop nls_iso8859_1 nls_cp437 vfat fat usb_storage libusual ppp_async crc_ccitt ppp_generic slhc af_packet i915 drm rfcomm sco bridge stp bnep l2cap binfmt_misc ppdev ipv6 acpi_cpufreq cpufreq_conservative cpufreq_stats cpufreq_ondemand cpufreq_userspace cpufreq_powersave freq_table pci_slot sbs sbshc container iptable_filter ip_tables x_tables uinput sbp2 parport_pc lp parport btusb bluetooth joydev pcmcia snd_hda_intel snd_pcm_oss snd_mixer_oss snd_pcm snd_seq_dummy snd_seq_oss snd_seq_midi snd_rawmidi arc4 ecb crypto_blkcipher snd_seq_midi_event snd_seq iwl3945 snd_timer snd_seq_device thinkpad_acpi mac80211 rfkill snd led_class sdhci_pci sdhci yenta_socket iTCO_wdt serio_raw battery ricoh_mmc mmc_core iTCO_vendor_support nvram cfg80211 psmouse evdev video ac bay rsrc_nonstatic pcmcia_core output soundcore button wmi pcspkr intel_agp agpgart snd_page_alloc shpchp pci_hotplug ext3 jbd mbcache sr_mod cdro Nov 3 08:02:04 platonas kernel: sd_mod crc_t10dif sg pata_acpi ata_piix ata_generic ohci1394 libata ieee1394 ehci_hcd scsi_mod uhci_hcd usbcore dock thermal processor fan fuse vesafb fbcon tileblit font bitblit softcursor [last unloaded: e1000] Nov 3 08:02:04 platonas kernel: [49099.700137] Pid: 0, comm: swapper Tainted: G W 2.6.27-7-generic #1 Nov 3 08:02:04 platonas kernel: [49099.700140] [<c037c406>] ?

At the moment Ethernet LEDs are both off, e1000e is loaded, and there are no more mutex contention messages in the log. I used wired Ethernet yesterday a couple of times and it worked fine. I'll try the upstream kernel if I see the problem again. -- e1000e mutex contention https://bugs.launchpad.net/bugs/291801 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
