Date: Sat, 14 Aug 2010 14:37:18 +0200 From: Sedat Dilek <sedat.dilek@...glemail.com> To: Greg KH <gregkh@...e.de>, LKML <linux-kernel@...r.kernel.org> Cc: penberg@...nel.org, arthur@....ro Subject: Re: Linux 2.6.35.2 [ CC me I am not subscribed to LKML ] [1] says: >You could try 'git bisect' between v2.6.35.1 and v2.6.35.2 to narrow >the problem down to a specific commit. I would suggest to revert last 3 patches to 2.6.35.y GIT branch (taken from upstream, recently accepted, not well tested?): x86: don't send SIGBUS for kernel page faults mm: fix missing page table unmap for stack guard page failure case mm: keep a guard page below a grow-down stack segment I can't understand why some days old upstream patches go into a stable-fix series. As far as I can see they were not in the review-2.6.35 cycle and not in 2.6.35.2-rc1 patch included (see my posting in [3],[4]). I see similiar Call trace(s) in 2.6.35-gitX (here on Debian/sid i386): root@...x:~# grep "Aug 14 13:00:5" /var/log/syslog Aug 14 13:00:53 tbox kernel: [ 1084.804086] BUG: scheduling while atomic: bash/3256/0x10000001 Aug 14 13:00:53 tbox kernel: [ 1084.804092] Modules linked in: btrfs zlib_deflate crc32c libcrc32c ufs qnx4 hfsplus hfs minix ntfs vfat msdos fat jfs xfs exportfs reiserfs ext2 acpi_cpufreq mperf cpufreq_stats cpufreq_userspace cpufreq_conservative cpufreq_powersave ppdev lp sco bnep l2cap bluetooth aes_i586 aes_generic ext4 jbd2 crc16 fuse dm_crypt snd_intel8x0 snd_intel8x0m snd_ac97_codec arc4 ecb ac97_bus radeon snd_pcm_oss snd_mixer_oss thinkpad_acpi snd_pcm ath5k snd_seq_midi snd_rawmidi mac80211 snd_seq_midi_event ttm snd_seq ath drm_kms_helper pcmcia drm joydev cfg80211 snd_timer snd_seq_device nsc_ircc yenta_socket rfkill pcmcia_rsrc i2c_algo_bit pcmcia_core snd i2c_i801 led_class video output irda rng_core soundcore tpm_tis shpchp i2c_core battery ac pci_hotplug tpm nvram pcspkr serio_raw parport_pc tpm_bios parport psmouse snd_page_alloc evdev processor button crc_ccitt ext3 jbd mbcache dm_mod usbhid hid sg sd_mod sr_mod cdrom crc_t10dif ata_generic ata_piix libata uhci_hcd ehci_hcd scsi_mod usbcore Aug 14 13:00:53 tbox kernel: e1000 floppy thermal thermal_sys nls_base [last unloaded: scsi_wait_scan] Aug 14 13:00:53 tbox kernel: [ 1084.804203] Pid: 3256, comm: bash Not tainted 2.6.35-git14.sd.1-686 #2 Aug 14 13:00:53 tbox kernel: [ 1084.804206] Call Trace: Aug 14 13:00:53 tbox kernel: [ 1084.804221] [<c12761ad>] ? schedule+0x8e/0x569 Aug 14 13:00:53 tbox kernel: [ 1084.804230] [<c108dc8c>] ? __alloc_pages_nodemask+0x565/0x5d7 Aug 14 13:00:53 tbox kernel: [ 1084.804235] [<c108a275>] ? generic_file_aio_read+0x581/0x5cc Aug 14 13:00:53 tbox kernel: [ 1084.804240] [<c1276793>] ? _cond_resched+0x26/0x3d Aug 14 13:00:53 tbox kernel: [ 1084.804247] [<c10a3b2e>] ? anon_vma_prepare+0x11/0xe6 Aug 14 13:00:53 tbox kernel: [ 1084.804251] [<c109fa93>] ? expand_downwards+0x15/0x122 Aug 14 13:00:53 tbox kernel: [ 1084.804255] [<c109ba49>] ? __pte_alloc+0x5a/0x8a Aug 14 13:00:53 tbox kernel: [ 1084.804271] [<c109d73b>] ? handle_mm_fault+0x207/0xa32 Aug 14 13:00:53 tbox kernel: [ 1084.804275] [<c109ac81>] ? follow_page+0x4d/0x29d Aug 14 13:00:53 tbox kernel: [ 1084.804279] [<c109e21e>] ? __get_user_pages+0x2b8/0x39b Aug 14 13:00:53 tbox kernel: [ 1084.804284] [<c10b9c24>] ? get_arg_page+0x2e/0x77 Aug 14 13:00:53 tbox kernel: [ 1084.804291] [<c1139d90>] ? strnlen_user+0x18/0x35 Aug 14 13:00:53 tbox kernel: [ 1084.804295] [<c10b9d33>] ? copy_strings+0xc6/0x161 Aug 14 13:00:53 tbox kernel: [ 1084.804299] [<c10ba9b1>] ? kernel_read+0x2d/0x3d Aug 14 13:00:53 tbox kernel: [ 1084.804303] [<c10b9de7>] ? copy_strings_kernel+0x19/0x27 Aug 14 13:00:53 tbox kernel: [ 1084.804307] [<c10bb1b1>] ? do_execve+0x143/0x24e Aug 14 13:00:53 tbox kernel: [ 1084.804313] [<c1007c82>] ? sys_execve+0x2c/0x4d Aug 14 13:00:53 tbox kernel: [ 1084.804318] [<c1002fee>] ? ptregs_execve+0x12/0x18 Aug 14 13:00:53 tbox kernel: [ 1084.804322] [<c1002f1f>] ? sysenter_do_call+0x12/0x28 Dunno, if they are correlated... - Sedat - [ REFERENCES ] [1] http://lkml.org/lkml/2010/8/14/46 [2] http://git.kernel.org/?p=linux/kernel/git/hpa/linux-2.6-allstable.git;a=shortlog;h=refs/heads/linux-2.6.35.y [3] http://lkml.org/lkml/2010/8/14/5 [4] http://lkml.org/lkml/2010/8/14/6 -- 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/
