Dear Maintainer, We experience problems with 3.16.0-8-amd64 in versions 3.16.64-1 and 3.16.64-2. Kernel oopses with 'unable to handle kernel paging request...' after some time, sometimes it takes 5 minutes for the error to appear, sometimes it take 2.5 days. One of the issues after that happens is that postfix is not able to talk to rspamd over milter interface any more. postfix/smtpd[2096]: warning: milter inet:localhost:11332: can't read SMFIC_OPTNEG reply packet header: Connection timed out This problem does not appear if we downgrade to 3.16.0-7-amd64 3.16.59-1. Regards Christian Rusa
I am experiencing the same identical problem. Running debian jessie on a Dell D430. I can reproducibly trigger this by doing python -c "import numpy" It does not happen if I roll back to linux-image-3.16.0-7-amd64 [ 1043.203200] BUG: unable to handle kernel paging request at ffff8820426d6138 [ 1043.203306] IP: [<ffffffff8108b912>] put_pid+0x12/0x50 [ 1043.203376] PGD 1b11067 PUD 0 [ 1043.203428] Oops: 0000 [#1] SMP [ 1043.203484] Modules linked in: btrfs xor raid6_pq ufs qnx4 hfsplus hfs minix ntfs vfat msdos fat jfs xfs libcrc32c crc32c_generic cpuid rfcomm ctr ccm pci_stub vboxpci(O) vboxnetadp(O) vboxnetflt(O) vboxdrv(O) bnep cpufreq_userspace cpufreq_stats cpufreq_powersave cpufreq_conservative binfmt_misc uinput i8k fuse lp iTCO_wdt iTCO_vendor_support dell_wmi sparse_keymap ppdev dell_laptop dcdbas ecb arc4 coretemp iwl4965 kvm_intel kvm iwl3945 iwlegacy btusb mac80211 bluetooth pcmcia 6lowpan_iphc cfg80211 evdev joydev serio_raw rfkill yenta_socket lpc_ich pcmcia_rsrc mfd_core pcmcia_core i915 snd_hda_codec_idt snd_hda_codec_generic rng_core snd_hda_intel snd_hda_controller wmi snd_hda_codec snd_hwdep button battery parport_pc drm_kms_helper snd_pcm parport tpm_tis drm snd_timer tpm i2c_algo_bit acpi_cpufreq [ 1043.204628] snd soundcore ac video processor shpchp ext4 crc16 mbcache jbd2 xts gf128mul algif_skcipher af_alg dm_crypt dm_mod sg sd_mod crc_t10dif crct10dif_generic crct10dif_common ata_generic mmc_block ata_piix firewire_ohci libata psmouse sdhci_pci sdhci mmc_core firewire_core crc_itu_t i2c_i801 scsi_mod i2c_core tg3 ptp pps_core libphy ehci_pci uhci_hcd ehci_hcd thermal thermal_sys usbcore usb_common [ 1043.205206] CPU: 0 PID: 12771 Comm: python Tainted: G O 3.16.0-8-amd64 #1 Debian 3.16.64-2 [ 1043.205281] Hardware name: Dell Inc.

Hi Nik, The pending update to 3.16.66 should fix this issue. If you can/want to pretest the packages for checking for further regression, see https://lists.debian.org/debian-lts/2019/05/msg00014.html . Hope this helps! Regards, Salvatore

Version: linux/3.16.68-1 I didn't find an upload for 3.16.66, but did find 3.16.68-1, so I'm closing the bug with that version
