I've tried with .31.1 too now and there does seem to be a scheduler component too. With .31.1 I also get the SKB allocation errors, but the desktop freeze seems to be less severe than with .32-rc3. I would suggest looking into that _after_ the allocation issue has been traced/solved. I did manage to really (partially) hang up the desktop with .31.1: music did not come back and the task manager of the KDE desktop remained frozen, but I could still use konsole [1]. I suspect this is because I also got an OOPS in between the SKB failures: IP: [] rpcauth_checkverf+0x4e/0x5a[sunrpc] PGD 77b83067 PUD 0 Oops: 0000 [#1] SMP last sysfs file: /sys/class/power_supply/C23D/charge_full CPU 0 Modules linked in: i915 drm i2c_algo_bit i2c_core ppdev parport_pc lp parport cpufreq_conservative cpufreq_userspace cpufreq_stats cpufreq_powersave ipv6 nfsd exportfs nfs lockd nfs_acl auth_rpcgss sunrpc ext2 coretemp hp_wmi acpi_cpufreq loop snd_hda_codec_analog snd_hda_intel snd_hda_codec arc4 snd_pcm_oss snd_mixer_oss ecb snd_pcm snd_seq_dummy snd_seq_oss iwlagn iwlcore snd_seq_midi pcmcia mac80211 snd_rawmidi usblp snd_seq_midi_event snd_seq pcspkr cfg80211 yenta_socket rsrc_nonstatic pcmcia_core psmouse snd_timer snd_seq_device rfkill serio_raw snd soundcore snd_page_alloc hp_accel lis3lv02d video container output wmi intel_agp input_polldev battery ac processor 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 sd_mod cdrom ide_pci_generic piix ide_core pata_acpi uhci_hcd ata_piix ohci1394 sdhci_pci sdhci mmc_core led_class ieee1394 ricoh_mmc ata_generic ehci_hcd libta e1000e scsi_mod thermal fan thermal_sys [last unloaded: scsi_wait_scan] Pid: 3226, comm: rpciod/0 Not tainted 2.6.31.1 #20 HP Compaq 2510p Notebook PC RIP: 0010:[] []rpcauth_checkverf+0x4e/0x5a [sunrpc] RSP: 0018:ffff88007aafbda0 EFLAGS: 00010246 RAX: 0000000400001000 RBX: ffff88003a718e40 RCX: 0000000000000001 RDX: ffff880038b821bc RSI: ffff880038b821c8 RDI: ffff8800618358c8 RBP: ffff88007aafbdc0 R08: 0000000000000000 R09: 0000000000000000 R10: ffff880001514d80 R11: ffff8800536401f0 R12: ffff8800618358c8 R13: ffff880038b821c8 R14: ffff880037bb4bd0 R15: ffffffffa04bf52b FS: 0000000000000000(0000) GS:ffff880001504000(0000) knlGS:0000000000000000 CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b CR2: 0000000400001038 CR3: 0000000067ee5000 CR4: 00000000000006f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process rpciod/0 (pid: 3226, threadinfo ffff88007aafa000, task ffff88007c431670) Stack: ffff88007aafbde0 ffff880037bb4bd0 ffff8800618358c8 ffff880061835958 <0> ffff88007aafbe00 ffffffffa043e24a ffff88007c4319e0 ffff8800618358c8 <0> ffff880061835970 ffff880061835958 0000000000000000 0000000000000001 Call Trace: [] call_decode+0x374/0x68e [sunrpc] [] __rpc_execute+0x86/0x244 [sunrpc] [] ? rpc_async_schedule+0x0/0x12 [sunrpc] [] rpc_async_schedule+0x10/0x12 [sunrpc] [] worker_thread+0x132/0x1ca [] ? autoremove_wake_function+0x0/0x38 [] ? worker_thread+0x0/0x1ca [] kthread+0x8f/0x97 [] child_rip+0xa/0x20 [] ? kthread+0x0/0x97 [] ? child_rip+0x0/0x20 Code: 30 0f b7 b7 06 01 00 00 48 89 d9 48 c7 c7 30 42 45 a0 48 8b 40 10 48 8b 50 10 31 c0 e8 73 f8 e0 e0 48 8b 43 38 4c 89 ee 4c 89 e7 50 38 41 59 5b 41 5c 41 5d c9 c3 55 48 89 e5 41 55 49 89 f5 RIP [] rpcauth_checkverf+0x4e/0x5a [sunrpc] RSP CR2: 0000000400001038 Not sure whether it's worth following up on that as a separate issue. Cheers, FJP [1] KDE's task manager freezing for short periods is normal for me while amarok is blocked by NFS. This normally only happens when I start amarok for the first time, but it does explain how the NFS oops can have the same effect. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
