Hi, two days ago I switched from 2.6.38-rc7 to 2.6.39-rc3. I have got a desktop monitor with built-in USB hub to which a built-in card reader and keyboard and mouse are attached. When I came home today in the evening and switched the monitor on, USB did not work anymore (could not use mouse and keyboard, also not if I plugged another keyboard into a different onboard USB port). Everything else still worked. Looking into it, I noticed that the cause was a bug that happened when I switched the monitor on (?) at noon: Apr 14 14:39:35 stein kernel: usb 1-2: new high speed USB device number 27 using ehci_hcd Apr 14 14:39:35 stein kernel: hub 1-2:1.0: USB hub found Apr 14 14:39:35 stein kernel: hub 1-2:1.0: 3 ports detected Apr 14 14:39:35 stein kernel: usb 1-2.1: new high speed USB device number 28 using ehci_hcd Apr 14 14:39:36 stein kernel: hub 1-2.1:1.0: USB hub found Apr 14 14:39:36 stein kernel: hub 1-2.1:1.0: 3 ports detected Apr 14 14:39:36 stein kernel: usb 1-2.2: new full speed USB device number 29 using ehci_hcd Apr 14 14:39:36 stein kernel: input: Logitech USB Gaming Mouse as /devices/pci0000:00/0000:00:12.2/usb1/1-2/1-2.2/1-2.2:1.0/input/input19 Apr 14 14:39:36 stein kernel: generic-usb 0003:046D:C042.0015: input: USB HID v1.11 Mouse [Logitech USB Gaming Mouse] on usb-0000:00:12.2-2.2/input0 Apr 14 14:39:36 stein kernel: generic-usb 0003:046D:C042.0016: claimed by neither input, hiddev nor hidraw Apr 14 14:39:36 stein kernel: usb 1-2.3: new low speed USB device number 30 using ehci_hcd Apr 14 14:39:36 stein kernel: input: HID 1267:0103 as /devices/pci0000:00/0000:00:12.2/usb1/1-2/1-2.3/1-2.3:1.0/input/input20 Apr 14 14:39:36 stein kernel: generic-usb 0003:1267:0103.0017: input: USB HID v1.10 Keyboard [HID 1267:0103] on usb-0000:00:12.2-2.3/input0 Apr 14 14:39:36 stein kernel: input: HID 1267:0103 as /devices/pci0000:00/0000:00:12.2/usb1/1-2/1-2.3/1-2.3:1.1/input/input21 Apr 14 14:39:36 stein kernel: generic-usb 0003:1267:0103.0018: input: USB HID v1.10 Device [HID 1267:0103] on usb-0000:00:12.2-2.3/input1 Apr 14 14:39:36 stein kernel: usb 1-2.1.1: new high speed USB device number 31 using ehci_hcd Apr 14 14:39:36 stein kernel: scsi14 : usb-storage 1-2.1.1:1.0 Apr 14 14:39:37 stein kernel: scsi 14:0:0:0: Direct-Access Generic Ultra HS-SD/MMC 1.88 PQ: 0 ANSI: 0 Apr 14 14:39:37 stein kernel: sd 14:0:0:0: Attached scsi generic sg5 type 0 Apr 14 14:39:37 stein kernel: sd 14:0:0:0: [sde] Attached SCSI removable disk Apr 14 14:39:37 stein kernel: ------------[ cut here ]------------ Apr 14 14:39:37 stein kernel: WARNING: at lib/kref.c:34 kref_get+0x23/0x2c() Apr 14 14:39:37 stein kernel: Hardware name: System Product Name Apr 14 14:39:37 stein kernel: Modules linked in: firewire_sbp2 firedtv dvb_core firewire_ohci firewire_core crc_itu_t cpufreq_ondemand powernow_k8 freq_table mperf snd_pcm_oss snd_mixer_oss snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device nfsd lockd it87 hwmon_vid sunrpc ext4 jbd2 crc16 sr_mod cdrom snd_hda_codec_realtek k10temp yenta_socket snd_hda_intel pcmcia_core pcmcia_rsrc snd_hda_codec snd_pcm pata_atiixp snd_timer sg snd snd_page_alloc r8169 mii processor usb_storage Apr 14 14:39:37 stein kernel: Pid: 10845, comm: kworker/3:1 Tainted: G W 2.6.39-rc3 #2 Apr 14 14:39:37 stein kernel: Call Trace: Apr 14 14:39:37 stein kernel: [<ffffffff81031ef9>] warn_slowpath_common+0x80/0x98 Apr 14 14:39:37 stein kernel: [<ffffffff81031f26>] warn_slowpath_null+0x15/0x17 Apr 14 14:39:37 stein kernel: [<ffffffff811398af>] kref_get+0x23/0x2c Apr 14 14:39:37 stein kernel: [<ffffffff811388be>] kobject_get+0x1a/0x22 Apr 14 14:39:37 stein kernel: [<ffffffff8125e65b>] get_device+0x14/0x1a Apr 14 14:39:37 stein kernel: [<ffffffff8126dec1>] scsi_request_fn+0x60/0x4cb Apr 14 14:39:37 stein kernel: [<ffffffff811279e1>] __blk_run_queue+0x7b/0xe9 Apr 14 14:39:37 stein kernel: [<ffffffff81129277>] blk_delay_work+0x26/0x37 Apr 14 14:39:37 stein kernel: [<ffffffff81046068>] process_one_work+0x243/0x3dd Apr 14 14:39:37 stein kernel: [<ffffffff81046007>] ?
