Same happens here with at least two different USB devices: usb 1-4.3: reset high speed USB device using ehci_hcd and address 5 usb 1-4.3: reset high speed USB device using ehci_hcd and address 6 usb 2-2: reset high speed USB device using ehci_hcd and address 6 usb 2-2: reset high speed USB device using ehci_hcd and address 7 usb 2-2: reset high speed USB device using ehci_hcd and address 9
While trying to use an USB device in VirtualBox (sometimes it works, sometimes it does not recognize the device in the VM) it got a little chattier: 09:39:50 simpad kernel: [ 8956.296858] ------------[ cut here ]------------ Oct 14 09:39:50 simpad kernel: [ 8956.296868] WARNING: at /build/buildd/linux-2.6.35/drivers/usb/host/ehci-hcd.c:1071 ehci_endpoint_reset+0xe2/0xf0() Oct 14 09:39:50 simpad kernel: [ 8956.296871] Hardware name: 64586QG Oct 14 09:39:50 simpad kernel: [ 8956.296873] clear_halt for a busy endpoint Oct 14 09:39:50 simpad kernel: [ 8956.296874] Modules linked in: isofs cdc_acm snd_usb_audio uvcvideo videodev snd_usbmidi_lib v4l1_compat nls_iso8859_1 nls_cp437 vfat nls_utf8 fat udf rfcomm binfmt_misc sco bnep l2cap vboxnetadp vboxnetflt vboxdrv deflate zlib_deflate ctr twofish twofish_common camellia serpent blowfish cast5 des_generic dm_crypt aes_i586 aes_generic xcbc rmd160 sha512_generic sha256_generic snd_hda_codec_analog nvidia(P) sha1_generic crypto_null af_key joydev usbhid hid snd_hda_intel snd_hda_codec snd_hwdep snd_pcm arc4 snd_seq_midi snd_rawmidi snd_seq_midi_event thinkpad_acpi iwlagn iwlcore pcmcia snd_seq snd_timer snd_seq_device mac80211 ppdev tpm_tis tpm parport_pc snd nvram tpm_bios cfg80211 r852 sm_common soundcore nand nand_ids nand_ecc yenta_socket pcmcia_rsrc psmouse snd_page_alloc mtd serio_raw pcmcia_core lp btusb parport bluetooth usb_storage firewire_ohci sdhci_pci sdhci ahci firewire_core led_class intel_agp crc_itu_t libahci e1000e video output agpgart Oct 14 09:39:50 simpad kernel: [ 8956.296963] Pid: 5054, comm: VirtualBox Tainted: P 2.6.35-22-generic #34-Ubuntu Oct 14 09:39:50 simpad kernel: [ 8956.296965] Call Trace: Oct 14 09:39:50 simpad kernel: [ 8956.296972] [<c014ac52>] warn_slowpath_common+0x72/0xa0 Oct 14 09:39:50 simpad kernel: [ 8956.296976] [<c0485c42>] ? ehci_endpoint_reset+0xe2/0xf0 Oct 14 09:39:50 simpad kernel: [ 8956.296979] [<c0485c42>] ? ehci_endpoint_reset+0xe2/0xf0 Oct 14 09:39:50 simpad kernel: [ 8956.296982] [<c014ad23>] warn_slowpath_fmt+0x33/0x40 Oct 14 09:39:50 simpad kernel: [ 8956.296985] [<c0485c42>] ehci_endpoint_reset+0xe2/0xf0 Oct 14 09:39:50 simpad kernel: [ 8956.296988] [<c046f0e6>] usb_hcd_reset_endpoint+0x26/0x80 Oct 14 09:39:50 simpad kernel: [ 8956.296991] [<c0472431>] usb_reset_endpoint+0x21/0x40 Oct 14 09:39:50 simpad kernel: [ 8956.296994] [<c047341f>] usb_clear_halt+0x6f/0x80 Oct 14 09:39:50 simpad kernel: [ 8956.296997] [<c047c682>] usbdev_do_ioctl+0x412/0xc60 Oct 14 09:39:50 simpad kernel: [ 8956.297001] [<c01743fb>] ? clockevents_program_event+0x8b/0x140 Oct 14 09:39:50 simpad kernel: [ 8956.297005] [<c017597e>] ? tick_program_event+0x2e/0x40 Oct 14 09:39:50 simpad kernel: [ 8956.297008] [<c047cedd>] usbdev_ioctl+0xd/0x10 Oct 14 09:39:50 simpad kernel: [ 8956.297011] [<c0226622>] vfs_ioctl+0x32/0xb0 Oct 14 09:39:50 simpad kernel: [ 8956.297014] [<c047ced0>] ? usbdev_ioctl+0x0/0x10 Oct 14 09:39:50 simpad kernel: [ 8956.297016] [<c0226eb9>] do_vfs_ioctl+0x79/0x2d0 Oct 14 09:39:50 simpad kernel: [ 8956.297019] [<c0227177>] sys_ioctl+0x67/0x80 Oct 14 09:39:50 simpad kernel: [ 8956.297022] [<c05cf79b>] ? smp_apic_timer_interrupt+0x5b/0x8a Oct 14 09:39:50 simpad kernel: [ 8956.297026] [<c05c9114>] syscall_call+0x7/0xb Oct 14 09:39:50 simpad kernel: [ 8956.297030] [<c05c0000>] ? cpu_init+0x207/0x249 Oct 14 09:39:50 simpad kernel: [ 8956.297032] ---[ end trace 757e5340b82a843e ]--- -- USB drive is randomly unmounted: reset high speed USB device using ehci_hcd https://bugs.launchpad.net/bugs/622494 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
