Bug#595187: linux-2.6: lots of OOPses on resume (NULL pointer dereference in file_ra_state_init)
Package: linux-2.6 Version: 2.6.32-21 i'm experiencing very similar issues, although also with earlier versions of linux-image-2.6.32-5-686. i first started having this problem after upgrading to squeeze from lenny, although i was running the exact same linux-image-2.6.32-* directly on lenny for quite some time without problems. i had been using uswsusp, but after experiencing this problem several times, i purged uswsusp and switched to using the in-kernel resume with pm-hibernate. an example OOPS below, if it's at all useful: Sep 5 19:00:35 mneme kernel: [ 7750.522234] BUG: unable to handle kernel NULL pointer dereference at 0010 Sep 5 19:00:35 mneme kernel: [ 7750.522243] IP: [c108cdc7] file_ra_state_init+0x3/0x18 Sep 5 19:00:35 mneme kernel: [ 7750.522256] *pde = Sep 5 19:00:35 mneme kernel: [ 7750.522261] Oops: [#3] SMP Sep 5 19:00:35 mneme kernel: [ 7750.522266] last sysfs file: /sys/devices/system/cpu/cpu1/cache/index2/shared_cpu_map Sep 5 19:00:35 mneme kernel: [ 7750.522272] Modules linked in: mct_u232 usbserial tun ip6table_filter ip6_tables iptable_filter ip_tables x_tables parport_pc ppdev lp parport sco bridge stp bnep rfcomm l2cap crc16 bluetooth acpi_cpufreq cpufreq_stats cpufreq_powersave cpufreq_conservative cpufreq_userspace kvm_intel kvm uinput fuse firewire_sbp2 loop snd_hda_codec_idt snd_hda_intel snd_hda_codec snd_hwdep snd_pcm_oss snd_mixer_oss snd_pcm snd_seq_midi snd_rawmidi snd_seq_midi_event snd_seq i915 snd_timer drm_kms_helper joydev snd_seq_device arc4 ecb drm b43 snd yenta_socket soundcore i2c_i801 i2c_algo_bit psmouse snd_page_alloc rsrc_nonstatic mac80211 dell_laptop i2c_core rng_core serio_raw evdev dcdbas video cfg80211 output button processor battery ac rfkill ext3 jbd mbcache sha256_generic aes_i586 aes_generic cbc dm_crypt dm_mod sd_mod crc_t10dif ata_generic ssb sdhci_pci sdhci ata_piix mmc_core firewire_ohci tg3 libata pcmcia thermal uhci_hcd led_class firewire_core crc_itu_t libphy scsi_mod ehci_hcd therma Sep 5 19:00:35 mneme kernel: l_sys pcmcia_core usbcore nls_base [last unloaded: scsi_wait_scan] Sep 5 19:00:35 mneme kernel: [ 7750.522412] Sep 5 19:00:35 mneme kernel: [ 7750.522418] Pid: 10665, comm: x-terminal-emul Tainted: G D(2.6.32-5-686 #1) Latitude D420 Sep 5 19:00:35 mneme kernel: [ 7750.522424] EIP: 0060:[c108cdc7] EFLAGS: 00210202 CPU: 1 Sep 5 19:00:35 mneme kernel: [ 7750.522429] EIP is at file_ra_state_init+0x3/0x18 Sep 5 19:00:35 mneme kernel: [ 7750.522434] EAX: ef7f45c8 EBX: ECX: d5699800 EDX: Sep 5 19:00:35 mneme kernel: [ 7750.522438] ESI: ef7f4580 EDI: EBP: f6f73b18 ESP: c49a3ea0 Sep 5 19:00:35 mneme kernel: [ 7750.522443] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 Sep 5 19:00:35 mneme kernel: [ 7750.522448] Process x-terminal-emul (pid: 10665, ti=c49a2000 task=efaa1100 task.ti=c49a2000) Sep 5 19:00:35 mneme kernel: [ 7750.522452] Stack: Sep 5 19:00:35 mneme kernel: [ 7750.522455] c10b114b f6f28080 f68bb220 c49a3f00 ef7f4580 c49a3f00 c49a3f00 0003 Sep 5 19:00:35 mneme kernel: [ 7750.522465] 0 c10b12ac ef7f4580 c10b4c40 f6cdfe80 c49a3f00 c10bb254 Sep 5 19:00:35 mneme kernel: [ 7750.522476] 0 0002 efa7a000 ff9c c1c7cbc0 b7112000 fffa0844 ef992898 Sep 5 19:00:35 mneme kernel: [ 7750.522488] Call Trace: Sep 5 19:00:35 mneme kernel: [ 7750.522495] [c10b114b] ? __dentry_open+0x176/0x246 Sep 5 19:00:35 mneme kernel: [ 7750.522502] [c10b12ac] ? nameidata_to_filp+0x29/0x3c Sep 5 19:00:35 mneme kernel: [ 7750.522509] [c10b4c40] ? chrdev_open+0x0/0x116 Sep 5 19:00:35 mneme kernel: [ 7750.522516] [c10bb254] ? do_filp_open+0x43f/0x802 Sep 5 19:00:35 mneme kernel: [ 7750.522524] [c10c2f65] ? alloc_fd+0x52/0xb7 Sep 5 19:00:35 mneme kernel: [ 7750.522530] [c10b0ee3] ? do_sys_open+0x4c/0xdf Sep 5 19:00:35 mneme kernel: [ 7750.522536] [c10b0fba] ? sys_open+0x1e/0x23 Sep 5 19:00:35 mneme kernel: [ 7750.522543] [c10030fb] ? sysenter_do_call+0x12/0x28 Sep 5 19:00:35 mneme kernel: [ 7750.522547] Code: c3 53 89 d3 ff 74 24 0c ff 74 24 0c e8 0e 93 fa ff 5a 59 85 c0 75 0e 85 db 74 0a c7 05 34 fc 4a c1 00 00 00 00 5b c3 90 8b 52 40 8b 52 10 c7 40 14 ff ff ff ff c7 40 18 ff ff ff ff 89 50 0c c3 Sep 5 19:00:35 mneme kernel: [ 7750.522607] EIP: [c108cdc7] file_ra_state_init+0x3/0x18 SS:ESP 0068:c49a3ea0 Sep 5 19:00:35 mneme kernel: [ 7750.522616] CR2: 0010 Sep 5 19:00:35 mneme kernel: [ 7750.522620] ---[ end trace f383376f90ced1d2 ]--- live well, vagrant -- Package-specific info: ** Version: Linux version 2.6.32-5-686 (Debian 2.6.32-21) (b...@decadent.org.uk) (gcc version 4.3.5 (Debian 4.3.5-2) ) #1 SMP Wed Aug 25 14:28:12 UTC 2010 ** Command line: BOOT_IMAGE=/vmlinuz-2.6.32-5-686 root=/dev/mapper/mneme-rwt ro quiet ** Not tainted ** Kernel log: [ 5400.080272] CPU: Physical Processor ID: 0 [ 5400.080272] CPU: Processor Core ID: 1 [ 5400.080272] CPU1:

[...] And did that make any difference? heh. sorry for being unclear :) unfortunately, no, it's still Oops'ing after resume. i also didn't mention, largely because i'm pretty unsure if it's really the case, but the issue *seems* to occur more reliably when hibernating (to disk) while on battery, but i'm really unsure of that. i'll see if i can more reliably trigger the same problem on a clean squeeze install on the same hardware in another partition... where i'm not as worried about crashing. live well, vagrant -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of unsubscribe.

Bug#595187: linux-2.6: lots of OOPses on resume (NULL pointer dereference in file_ra_state_init)
Source: linux-2.6 Version: 2.6.32-21 Severity: normal Hi, Since the upgrade from 2.6.32-20 - 2.6.32-21, my laptop fails to resume properly into Xorg : the cursor only appears when I move it and there is nothing much more I can do than switching to the console, login as root and reboot. In the console, I can see a lot of OOpses that are visible in the attached log file. This did not happend with 2.6.32-20, or at least not before many suspend cycles.
