apport information ** Description changed:
Occasionally I get my machine hung completely. Fortunately, I've got and saved oops listing using netconsole before hang, and here it is [1]. Here is little piece of oops from the link above: === [15051.270461] BUG: unable to handle kernel paging request at 00000000ff5ae8e4 [15051.271583] IP: [<ffffffff8109ae6e>] srcu_notifier_call_chain+0xe/0x20 … [15051.956205] Call Trace: [15051.980641] [<ffffffff81606085>] ? __cpufreq_notify_transition+0x95/0x1e0 [15052.005640] [<ffffffff816081ee>] cpufreq_notify_transition+0x3e/0x70 [15052.030240] [<ffffffff816083d8>] cpufreq_freq_transition_begin+0xe8/0x130 [15052.054522] [<ffffffff813b8940>] ? ucs2_strncmp+0x70/0x70 [15052.078208] [<ffffffff816089bf>] __target_index+0xbf/0x1a0 [15052.101348] [<ffffffff81608b9c>] __cpufreq_driver_target+0xfc/0x160 [15052.124250] [<ffffffff8160b0d4>] od_check_cpu+0xa4/0xb0 [15052.146789] [<ffffffff8160c9ec>] dbs_check_cpu+0x16c/0x1c0 [15052.168935] [<ffffffff8160b4dd>] od_dbs_timer+0x11d/0x180 [15052.190607] [<ffffffff8108e6ff>] process_one_work+0x17f/0x4c0 [15052.211825] [<ffffffff8108f46b>] worker_thread+0x11b/0x3f0 [15052.232490] [<ffffffff8108f350>] ? create_and_start_worker+0x80/0x80 [15052.253127] [<ffffffff81096479>] kthread+0xc9/0xe0 [15052.273292] [<ffffffff810963b0>] ? flush_kthread_worker+0xb0/0xb0 [15052.293487] [<ffffffff81793efc>] ret_from_fork+0x7c/0xb0 [15052.313544] [<ffffffff810963b0>] ? flush_kthread_worker+0xb0/0xb0 … === Also here is my lspci [2] and cpuinfo [3] as well. Vanilla 3.15.8 and 3.16.0 are affected as well as latest Ubuntu 3.13 kernel. No visible reason to trigger the bug. After hang machine doesn't respond via network, there's no disk IO, and also it doesn't respond to pressing power button in order to perform soft off. And here is kernel bugzilla bugreport [4].
