Bug#803677: linux-image-4.2.0-1-amd64: frequent stalling of whole machine since upgrade from kernel 4.1 to 4.2
Package: src:linux Version: 4.2.3-2 Severity: important Dear Maintainer, since upgrading from kernel 4.1 to 4.2 I'm experiencing frequent stalls, which make the whole computer stop doing anything. On pressing a keyboard key or (but that works only sometimes) moving the mouse, it continues. dmesg is flooded with messages about "INFO: rcu_sched self-detected stall on CPU", see below. This is escpescially annoying when trying to shutdown the machine as I have to literally have to keep typing on the keyboard until the machine powers off. - Tim *** Reporter, please consider answering these questions, where appropriate *** * What led up to the situation? * What exactly did you do (or not do) that was effective (or ineffective)? * What was the outcome of this action? * What outcome did you expect instead? *** End of the template - remove these template lines *** -- Package-specific info: ** Version: Linux version 4.2.0-1-amd64 (debian-kernel@lists.debian.org) (gcc version 4.9.3 (Debian 4.9.3-4) ) #1 SMP Debian 4.2.3-2 (2015-10-14) ** Command line: BOOT_IMAGE=/vmlinuz-4.2.0-1-amd64 root=UUID=a411f5e5-1753-4263-a89c-ee3f5b02f0b4 ro quiet init=/bin/systemd ** Not tainted ** Kernel log: [13978.977523] 0003 81a54ec0 810c63e0 2951 [13978.977529] 88022fd16580 81a54ec0 81b06d00 [13978.977535] 810c9581 007e 03b7 8101c7d4 [13978.977541] Call Trace: [13978.977544][] ? rcu_dump_cpu_stacks+0x80/0xb0 [13978.977555] [] ? rcu_check_callbacks+0x421/0x6e0 [13978.977562] [] ? native_sched_clock+0x24/0x80 [13978.977569] [] ? sched_clock+0x5/0x10 [13978.977576] [] ? tick_sched_do_timer+0x40/0x40 [13978.977583] [] ? update_process_times+0x36/0x60 [13978.977589] [] ? tick_sched_handle.isra.15+0x24/0x60 [13978.977595] [] ? tick_sched_timer+0x3b/0x70 [13978.977600] [] ? __hrtimer_run_queues+0xdc/0x210 [13978.977607] [] ? read_tsc+0x5/0x10 [13978.977613] [] ? hrtimer_interrupt+0x9a/0x190 [13978.977620] [] ? smp_apic_timer_interrupt+0x39/0x50 [13978.977627] [] ? apic_timer_interrupt+0x6b/0x70 [13978.977630][] ? __setup_APIC_LVTT+0x6c/0x110 [13978.977642] [] ? native_safe_halt+0x2/0x10 [13978.977648] [] ? default_idle+0x1c/0xa0 [13978.977655] [] ? amd_e400_idle+0x65/0xe0 [13978.977662] [] ? cpu_startup_entry+0x2b4/0x310 [13978.977669] [] ? start_secondary+0x178/0x1a0 [13978.977673] Task dump for CPU 3: [13978.977676] swapper/3 R running task0 0 1 0x0008 [13978.977682] 81ccadc4 ffcf 81056bc2 0010 [13978.977688] 0292 880226227e90 0018 8101d6fc [13978.977694] 880226228000 0003 880226228000 8101d7e5 [13978.977700] Call Trace: [13978.977706] [] ? native_safe_halt+0x2/0x10 [13978.977713] [] ? default_idle+0x1c/0xa0 [13978.977720] [] ? amd_e400_idle+0x65/0xe0 [13978.977726] [] ? cpu_startup_entry+0x2b4/0x310 [13978.977733] [] ? start_secondary+0x178/0x1a0 [13978.977740] Task dump for CPU 0: [13978.977745] swapper/0 R running task0 0 0 0x0008 [13978.977754] 81ccadc4 ff10 81056bc2 0010 [13978.977763] 0296 81a03eb0 0018 8101d6fc [13978.90] 81a04000 81a04000 8101d7e5 [13978.96] Call Trace: [13978.977791] [] ? native_safe_halt+0x2/0x10 [13978.977802] [] ? default_idle+0x1c/0xa0 [13978.977809] [] ? amd_e400_idle+0x65/0xe0 [13978.977818] [] ? cpu_startup_entry+0x2b4/0x310 [13978.977828] [] ? start_kernel+0x480/0x48b [13978.977835] [] ? early_idt_handler_array+0x120/0x120 [13978.977843] [] ? early_idt_handler_array+0x120/0x120 [13978.977850] [] ? x86_64_start_kernel+0x148/0x157 [13978.977854] Task dump for CPU 1: [13978.977857] swapper/1 R running task0 0 1 0x0008 [13978.977865] 81ccadc4 ff10 81056bc2 0010 [13978.977871] 0292 88022621fe90 0018 8101d6fc [13978.977877] 88022622 0001 88022622 8101d7e5 [13978.977883] Call Trace: [13978.977890] [] ? native_safe_halt+0x2/0x10 [13978.977897] [] ? default_idle+0x1c/0xa0 [13978.977904] [] ? amd_e400_idle+0x65/0xe0 [13978.977911] [] ? cpu_startup_entry+0x2b4/0x310 [13978.977920] [] ? start_secondary+0x178/0x1a0 [13978.977924] Task dump for CPU 2: [13978.977928] swapper/2 R running task0 0 1 0x0008 [13978.977934] 81ccadc4 ff10 81056bc2 0010 [13978.977940] 0292 880226223e90 0018 8101d6fc [13978.977946] 880226224000 0002 880226224000 8101d7e5 [13978.977951] Call Trace: [13978.977958] [] ? native_safe_halt+0x2/0x10 [13978.977965] [] ?

Bug#803739: cosmetic: /initrd.img /vmlinuz smylinks - absolute vs. relative
Source: linux Severity: minor Hey. This is absolutely just cosmetic ;-) I've noted that the symlink /initrd.img is always absolute, while /vmlinuz is always relative, e.g.: $ ls -al /initrd.img /vmlinuz lrwxrwxrwx 1 root root 30 Sep 27 13:37 /initrd.img -> /boot/initrd.img-4.2.0-1-amd64 lrwxrwxrwx 1 root root 26 Sep 27 13:37 /vmlinuz -> boot/vmlinuz-4.2.0-1-amd64 Unless this has some secret reason,... it may be aligned for cosmetic reasons. Cheers, Chris.
