Date: Thu, 6 Mar 2008 13:14:11 +0100 From: "Szekeres István" <szekeres@....hu> To: linux-kernel@...r.kernel.org Cc: a.p.zijlstra@...llo.nl, mingo@...e.hu Subject: Lockdep warning Found this on my computer after an uptime of 7 days. I don't know if it is harmless or not. "dirty" is only because of an uncommitted HID input quirk entry. Config is available if needed. ------------[ cut here ]------------ WARNING: at kernel/lockdep.c:2662 check_flags+0x13b/0x160() Modules linked in: tsl2550 pcf8591 pcf8575 pcf8574 max6875 eeprom ds1682 i2c_via i2c_algo_bit i2c_dev nls_iso8859_1 nls_cp437 vfat fat nls_base sg sd_mod usb_storage libusual usbhid rfcomm l2cap bluetooth video output sbs sbshc container dock backlight ac battery joydev evdev 8250_pnp 8250 serial_core psmouse rtc serio_raw pcspkr snd_via82xx snd_ac97_codec ac97_bus snd_pcm snd_page_alloc snd_mpu401_uart snd_seq_midi snd_rawmidi snd_seq_midi_event snd_seq snd_timer snd_seq_device snd soundcore i2c_viapro i2c_core hid button floppy ehci_hcd uhci_hcd usbcore dm_mirror dm_snapshot dm_mod unix thermal processor fan fuse [last unloaded: usbhid] Pid: 24638, comm: totem Not tainted 2.6.25-rc3pista-00081-g7704a8b-dirty #14 [warn_on_slowpath+84/112] warn_on_slowpath+0x54/0x70 [native_calculate_cpu_khz+240/352] ? native_calculate_cpu_khz+0xf0/0x160 [unqueue_me+63/128] ? unqueue_me+0x3f/0x80 [_spin_unlock+39/80] ? _spin_unlock+0x27/0x50 [unqueue_me+71/128] ? unqueue_me+0x47/0x80 [futex_wait+566/768] ? futex_wait+0x236/0x300 [check_flags+315/352] check_flags+0x13b/0x160 [lock_acquire+65/160] lock_acquire+0x41/0xa0 [down_read+61/128] down_read+0x3d/0x80 [futex_wake+46/240] ? futex_wake+0x2e/0xf0 [futex_wake+46/240] futex_wake+0x2e/0xf0 [do_futex+163/2688] do_futex+0xa3/0xa80 [do_notify_resume+97/1968] ? do_notify_resume+0x61/0x7b0 [sysenter_past_esp+157/165] ? sysenter_past_esp+0x9d/0xa5 [search_exception_tables+23/48] ? search_exception_tables+0x17/0x30 [fixup_exception+14/48] ? fixup_exception+0xe/0x30 [do_general_protection+343/656] ? do_general_protection+0x157/0x290 [ktime_get_ts+59/64] ? ktime_get_ts+0x3b/0x40 [ktime_get+17/48] ? ktime_get+0x11/0x30 [sys_futex+138/240] sys_futex+0x8a/0xf0 [sysenter_past_esp+95/165] sysenter_past_esp+0x5f/0xa5 ======================= ---[ end trace cf60772f91bc8ecf ]--- possible reason: unannotated irqs-on. irq event stamp: 21512 hardirqs last enabled at (21511): [sysenter_past_esp+154/165] sysenter_past_esp+0x9a/0xa5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
