I run a kernel with pr_alert() for several times > and here is the screen log. Note that this kernel is compiled with gcc > 4.6.3 and the decoded code looks different than gcc 4.8.1 I got a call trace containing parport_pc_probe_port() (is it the culprit?) after recompiling kernel with CONFIG_DEBUG_OBJECTS_TIMERS=y and booting with "ignore_loglevel". Here is the log for two kernel boots. wfg@bee ~/linux/obj-compiletest% kvm-0day.sh arch/x86/boot/bzImage [ 0.000000] Initializing cgroup subsys cpuset [ 0.000000] Initializing cgroup subsys cpu [ 0.000000] Linux version 3.11.0-rc2-00010-gc817a67-dirty (wfg@bee) (gcc version 4.6.3 (Debian 4.6.3-1) ) #6 SMP PREEMPT Tue Oct 8 10:03:08 CST 2013 [ 0.000000] Command line: hung_task_panic=1 rcutree.rcu_cpu_stall_timeout=100 log_buf_len=8M debug sched_debug ignore_loglevel apic=debug dynamic_printk sysrq_always_enabled panic=10 prompt_ramdisk=0 console=ttyS0,115200 console=tty0 vga=normal root=/dev/ram0 rw [ 0.000000] e820: BIOS-provided physical RAM map: [ 0.000000] BIOS-e820: [mem 0x0000000000000000-0x000000000009fbff] usable [ 0.000000] BIOS-e820: [mem 0x000000000009fc00-0x000000000009ffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000000f0000-0x00000000000fffff] reserved [ 0.000000] BIOS-e820: [mem 0x0000000000100000-0x000000000fffdfff] usable [ 0.000000] BIOS-e820: [mem 0x000000000fffe000-0x000000000fffffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000feffc000-0x00000000feffffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fffc0000-0x00000000ffffffff] reserved [ 0.000000] debug: ignoring loglevel setting.
