It seems to occur only when mounting or remounting an ext4 partition using the auto_da_alloc ext4 mount option. Without this option, the warning doesn't occur. I'm using x86_64 Debian testing with a 2.6.31.6 kernel compiled from vanilla kernel.org sources running an a Samsung R560 laptop. This is what I see in the syslog: Nov 17 22:03:41 callisto kernel: [ 19.128673] WARNING: at mm/page_alloc.c:1751 __alloc_pages_nodemask+0x174/0x592() Nov 17 22:03:41 callisto kernel: [ 19.152057] Hardware name: R560 Nov 17 22:03:41 callisto kernel: [ 19.175684] Modules linked in: ext4 jbd2 crc16 fuse coretemp loop btusb bluetooth arc4 ecb snd_hda_codec_nvhdmi snd_hda_codec_realtek iwlagn iwlcore snd_hda_intel joydev snd_hda_codec snd_hwdep snd_pcm_oss snd_mixer_oss led_class snd_pcm snd_seq_dummy snd_seq_oss mac80211 snd_seq_midi snd_rawmidi sg snd_seq_midi_event snd_seq snd_timer snd_seq_device cfg80211 snd i2c_i801 sr_mod soundcore uhci_hcd rfkill i2c_core psmouse cdrom intel_agp snd_page_alloc ehci_hcd sky2 evdev serio_raw video battery pcspkr output button ac aes_x86_64 aes_generic xts gf128mul dm_crypt dm_mod sd_mod crc_t10dif fan ahci ext3 jbd mbcache Nov 17 22:03:41 callisto kernel: [ 19.255394] Pid: 1553, comm: mount Not tainted 2.6.31.6 #1 Nov 17 22:03:41 callisto kernel: [ 19.282323] Call Trace: Nov 17 22:03:41 callisto kernel: [ 19.308744] [<ffffffff810a7e87>] ? __alloc_pages_nodemask+0x174/0x592 Nov 17 22:03:41 callisto kernel: [ 19.335479] [<ffffffff810412da>] warn_slowpath_common+0x77/0xa4 Nov 17 22:03:41 callisto kernel: [ 19.361993] [<ffffffff81041316>] warn_slowpath_null+0xf/0x11 Nov 17 22:03:41 callisto kernel: [ 19.388272] [<ffffffff810a7e87>] __alloc_pages_nodemask+0x174/0x592 Nov 17 22:03:41 callisto kernel: [ 19.414627] [<ffffffff8105de26>] ? getnstimeofday+0x57/0xb3 Nov 17 22:03:41 callisto kernel: [ 19.441186] [<ffffffff810a830e>] __get_free_pages+0x12/0x4f Nov 17 22:03:41 callisto kernel: [ 19.467454] [<ffffffff810ccff2>] __kmalloc+0x45/0x132 Nov 17 22:03:41 callisto kernel: [ 19.493497] [<ffffffff8117703e>] match_number+0x35/0x98 Nov 17 22:03:41 callisto kernel: [ 19.519417] [<ffffffff811770cc>] match_int+0xb/0xd Nov 17 22:03:41 callisto kernel: [ 19.545047] [<ffffffffa0382a1b>] parse_options+0x61b/0x73e [ext4] Nov 17 22:03:41 callisto kernel: [ 19.570632] [<ffffffff810f30da>] ? __wait_on_buffer+0x1f/0x21 Nov 17 22:03:41 callisto kernel: [ 19.596161] [<ffffffff810f3101>] ? wait_on_buffer+0x25/0x29 Nov 17 22:03:41 callisto kernel: [ 19.621468] [<ffffffffa0383411>] ext4_fill_super+0x368/0x20c2 [ext4] Nov 17 22:03:41 callisto kernel: [ 19.646600] [<ffffffff81176135>] ? snprintf+0x59/0x5b Nov 17 22:03:41 callisto kernel: [ 19.671431] [<ffffffff8117063b>] ? kobject_get+0x1a/0x22 Nov 17 22:03:41 callisto kernel: [ 19.696013] [<ffffffff810f7b54>] ? __blkdev_get+0x2a7/0x35a Nov 17 22:03:41 callisto kernel: [ 19.720428] [<ffffffff812ca16a>] ? down_write+0x19/0x1d Nov 17 22:03:41 callisto kernel: [ 19.744514] [<ffffffff810d5bc7>] get_sb_bdev+0x119/0x162 Nov 17 22:03:41 callisto kernel: [ 19.768211] [<ffffffffa03830a9>] ? ext4_fill_super+0x0/0x20c2 [ext4] Nov 17 22:03:41 callisto kernel: [ 19.791875] [<ffffffffa0380df3>] ext4_get_sb+0x13/0x15 [ext4] Nov 17 22:03:41 callisto kernel: [ 19.815571] [<ffffffff810d57fa>] vfs_kern_mount+0x99/0x11d Nov 17 22:03:41 callisto kernel: [ 19.839280] [<ffffffff810d58db>] do_kern_mount+0x47/0xe7 Nov 17 22:03:41 callisto kernel: [ 19.862943] [<ffffffff810ea17f>] do_mount+0x74b/0x7b9 Nov 17 22:03:41 callisto kernel: [ 19.886475] [<ffffffff810a830e>] ? __get_free_pages+0x12/0x4f Nov 17 22:03:41 callisto kernel: [ 19.910076] [<ffffffff810ea26d>] sys_mount+0x80/0xc3 Nov 17 22:03:41 callisto kernel: [ 19.933491] [<ffffffff8104c3d3>] ? sys_rt_sigprocmask+0x54/0xcf Nov 17 22:03:41 callisto kernel: [ 19.956952] [<ffffffff8100baeb>] system_call_fastpath+0x16/0x1b Nov 17 22:03:41 callisto kernel: [ 19.980419] ---[ end trace 7a506926f0515111 ]--- Nov 17 22:03:41 callisto kernel: [ 20.060709] EXT4-fs (dm-3): barriers enabled Nov 17 22:03:41 callisto kernel: [ 20.100150] kjournald2 starting: pid 1579, dev dm-3:8, commit interval 5 seconds Nov 17 22:03:41 callisto kernel: [ 20.124074] EXT4-fs (dm-3): internal journal on dm-3:8 Nov 17 22:03:41 callisto kernel: [ 20.147399] EXT4-fs (dm-3): delayed allocation enabled Nov 17 22:03:41 callisto kernel: [ 20.147616] EXT4-fs: file extents enabled Nov 17 22:03:41 callisto kernel: [ 20.148116] EXT4-fs: mballoc enabled Nov 17 22:03:41 callisto kernel: [ 20.148127] EXT4-fs (dm-3): mounted filesystem with ordered data mode -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
