Date: Wed, 21 Jan 2009 14:14:17 +0100 From: Frans Pop <elendil@...net.nl> To: "Rafael J. Wysocki" <rjw@...k.pl> Cc: linux-kernel@...r.kernel.org Subject: WARNING: at drivers/pci/pci-driver.c:368 pci_legacy_suspend+0x7b/0xb8() Hi Rafael, My last suspend to RAM gave me the WARN below. This is with 2.6.28-rc2 with the following patches on top: * hp-wmi: fix regressions caused by missing if statement * double disk spin off fix: Hibernation: Introduce system_entering_hibernation DMI: Introduce dmi_first_match to make the interface more flexible SATA: Blacklisting of systems that spin off disks during ACPI power off SATA AHCI: Blacklist system that spins off disks during ACPI power off SATA Sil: Blacklist system that spins off disks during ACPI power off SATA PIIX: Blacklist system that spins off disks during ACPI power off * selected patches based on regression overview: USB: Fix suspend-resume of PCI USB controllers Revert "x86: signal: change type of paramter for sys_rt_sigreturn()" USB: don't enable wakeup by default for PCI host controllers work_on_cpu: dont try to get_online_cpus() in work_on_cpu. PCI PM: Restore standard config registers of all devices early I suspect the cause to be the last patch, as an earlier suspend which I did without that patch did not result in the warning. ricoh-mmc: Suspending. ricoh-mmc: Controller is now re-enabled. ------------[ cut here ]------------ WARNING: at drivers/pci/pci-driver.c:368 pci_legacy_suspend+0x7b/0xb8() Hardware name: HP Compaq 2510p Notebook PC Modules linked in: tcp_diag inet_diag i915 drm i2c_algo_bit i2c_core ppdev parport_pc lp parport ipv6 nfs lockd nfs_acl auth_rpcgss sunrpc ext2 coretemp hp_wmi acpi_cpufreq loop snd_hda_codec_analog snd_hda_intel snd_hda_codec snd_pcm_oss snd_mixer_oss snd_pcm snd_seq_dummy snd_seq_oss arc4 snd_seq_midi snd_rawmidi ecb snd_seq_midi_event snd_seq iwlagn iwlcore snd_timer snd_seq_device rfkill snd lib80211 mac80211 serio_raw soundcore pcmcia snd_page_alloc hp_accel cfg80211 psmouse pcspkr iTCO_wdt yenta_socket rsrc_nonstatic pcmcia_core usblp intel_agp wmi video output lis3lv02d container battery ac button joydev evdev ext3 jbd mbcache sha256_generic aes_x86_64 aes_generic cbc usbhid hid dm_crypt dm_mirror dm_region_hash dm_log dm_snapshot dm_mod sg sr_mod cdrom sd_mod piix ide_pci_generic ata_piix ide_core pata_acpi ohci1394 sdhci_pci sdhci ieee1394 mmc_core led_class ricoh_mmc ata_generic ehci_hcd libata uhci_hcd e1000e scsi_mod thermal processor fan thermal_sys Pid: 6325, comm: s2ram Not tainted 2.6.29-rc2 #7 Call Trace: [<ffffffff802398cf>] warn_slowpath+0xd3/0x10f [<ffffffff8035ae2b>] ? acpi_ns_get_node+0x92/0xa1 [<ffffffff80444232>] ? printk+0x67/0x6d [<ffffffff8032c1cc>] ? pci_bus_write_config_byte+0x59/0x67 [<ffffffffa00bc2d5>] ? ricoh_mmc_enable+0x13c/0x145 [ricoh_mmc] [<ffffffff80331894>] pci_legacy_suspend+0x7b/0xb8 [<ffffffff803319c4>] pci_pm_suspend+0x34/0x86 [<ffffffff8039929a>] pm_op+0x52/0xe5 [<ffffffff80399844>] device_suspend+0x32e/0x453 [<ffffffff8025f39e>] suspend_devices_and_enter+0x3e/0x12e [<ffffffff8025f5f6>] enter_state+0x110/0x164 [<ffffffff8025f701>] state_store+0xb7/0xd7 [<ffffffff8032069f>] kobj_attr_store+0x17/0x19 [<ffffffff802e1de9>] sysfs_write_file+0xdf/0x114 [<ffffffff8029723b>] vfs_write+0xa7/0xe1 [<ffffffff80297339>] sys_write+0x47/0x6f [<ffffffff8020c25b>] system_call_fastpath+0x16/0x1b ---[ end trace 7b44d6d0be5818c2 ]--- -- 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/
