Hi, I am seeing random lockups/crashes on my home server with kernel 3.10.92/3 and 3.14.56/7. Both have been compiled with gcc 5.2. The machine usually locks up within a few minutes. 4.1.13 has run for over 5 days without problems ruling out hardware problems. Compiling 3.10.93 with gcc 4.8.5 also has no problems (and has also been up 5 days), seems like this is caused by compiling with gcc 5.2. If more information is needed please let me know. Thanks! config for 3.14 is here https://aur.archlinux.org/cgit/aur.git/tree/config?h=linux-lts314&id=d5f173168d478646f576250295c3c4467fea93a5 config for 3.10 is here https://aur.archlinux.org/cgit/aur.git/tree/config?h=linux-lts310&id=263739cc4837df1466732d66e0164e44f40d488e 3.10 also has two patches to fix compilation with gcc5 http://kernel.opensuse.org/cgit/kernel/patch/?id=54c2f3fdb941204cad136024c7b854b7ad112ab6 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/drivers/lguest/x86/core.c?id=cdd77e87eae52b7251acc5990207a1c4500a84ce cat /proc/cmdline BOOT_IMAGE=../vmlinuz-linux-lts root=UUID=8e3f3437-37e7-4f2d-9c45-b59037577bea ipv6.disable=1 nomodeset panic=60 debug ignore_loglevel rw initrd=../initramfs-linux-lts-fallback.img cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 6 model : 8 model name : AMD Sempron(tm) 2600+ stepping : 1 cpu MHz : 1837.000 cache size : 256 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fdiv_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 mmx fxsr sse syscall mp mmxext 3dnowext 3dnow 3dnowprefetch vmmcall bugs : fxsave_leak sysret_ss_attrs bogomips : 3666.79 clflush size : 32 cache_alignment : 32 address sizes : 34 bits physical, 32 bits virtual power management: ts -------------------------------------------------------------------------------- 3.14.56 [ 187.246658] general protection fault: 0000 [#1] SMP [ 187.246813] Modules linked in: netconsole cfg80211 rfkill nouveau mxm_wmi wmi video snd_wavefront ttm drm_kms_helper snd_cs4236 snd_wss_lib drm mac_hid evdev ppdev snd_opl3_lib snd_hwdep hwmon snd_pcm i2c_algo_bit snd_timer 8139too e100 8139cp pcspkr snd_mpu401_uart serio_raw mii snd_rawmidi snd_seq_device snd soundcore ns558 gameport cpufreq_nforce2 parport_pc i2c_nforce2 nvidia_agp parport agpgart i2c_core shpchp button processor sch_fq_codel ip_tables x_tables ext4 crc16 mbcache jbd2 sd_mod crc_t10dif crct10dif_common ata_generic pata_acpi pata_amd libata scsi_mod atkbd libps2 i8042 serio [ 187.249470] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 3.14.56-1-lts314 #1 [ 187.249526] Hardware name: /nVidia-nForce2, BIOS F2 10/26/2004 [ 187.249581] task: c15ef9c0 ti: c16f8000 task.ti: c15e4000 [ 187.249637] EIP: 0060:[<c103e5ca>] EFLAGS: 00014082 CPU: 0 [ 187.249697] EIP is at doublefault_fn+0x1a/0x140 [ 187.249749] EAX: 00000000 EBX: 00000000 ECX: 00000000 EDX: 00000000 [ 187.249803] ESI: 00000000 EDI: 00000000 EBP: c16f90d8 ESP: c16f90b0 [ 187.249859] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 [ 187.249913] CR0: 8005003b CR2: c15e3ef8 CR3: 016eb000 CR4: 000007d0 [ 187.249966] Stack: [ 187.250015] 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 [ 187.250392] 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 [ 187.250763] 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 [ 187.251134] Call Trace: [ 187.251211] Code: 10 10 00 00 3e 8d 74 26 00 e8 d3 9f fc ff 5d c3 90 55 89 e5 56 53 81 ec 30 10 00 00 83 0c 24 00 81 c4 10 10 00 00 3e 8d 74 26 00 <65> a1 14 00 00 00 89 45 f4 31 c0 31 c0 c7 45 f0 00 00 00 00 66 [ 187.253864] EIP: [<c103e5ca>] doublefault_fn+0x1a/0x140 SS:ESP 0068:c16f90b0 [ 187.254000] ---[ end trace 2be0ef59392bd46e ]--- [ 187.254056] Kernel panic - not syncing: Attempted to kill the idle task!
