Hello, I do not remember when I see last term syslogd printing messages on the terminal in X (konsole in KDE to be precise). But I do remember that these messages indicated serious issues :0(
The worst thing is I do not even understand what the system wanted to tell me. >From the syslog, I can speculate on a rcu_sched self-detect stall (therefore I copied debian-kernel). I am running kernel 3.13 since a few days. Can anybody help here? I attach the console output and the relevant section of /var/log/syslog Console output: Message from syslogd@www at Fri Mar 21 14:28:50 2014 ... www vmunix: [118396.260001] CPU: 0 PID: 29 Comm: kswapd0 Tainted: G C O 3.13-1-686-pae #1 Debian 3.13.5-1 Message from syslogd@www at Fri Mar 21 14:29:10 2014 ... www vmunix: [118396.260001] Hardware name: System manufacturer P5E-VM HDMI/P5E-VM HDMI, BIOS 0405 12/17/2007 Message from syslogd@www at Fri Mar 21 14:29:10 2014 ... www vmunix: [118396.260001] task: f75344a0 ti: f76d6000 task.ti: f76d6000 Message from syslogd@www at Fri Mar 21 14:29:10 2014 ... www vmunix: [118396.260001] Stack: Message from syslogd@www at Fri Mar 21 14:29:10 2014 ... www vmunix: [118396.260001] Call Trace: Message from syslogd@www at Fri Mar 21 14:29:10 2014 ... www vmunix: [118396.260001] Code: 00 48 75 fd 48 c3 8d 74 26 00 8d bc 27 00 00 00 00 ff 15 30 0c 59 c1 f3 c3 90 8d b4 26 00 00 00 00 c1 e0 02 64 8b 15 9c be 63 c1 <6b> d2 3e f7 e2 8d 42 01 ff 15 30 0c 59 c1 f3 c3 8d b6 00 00 00 Message from syslogd@www at Fri Mar 21 14:29:10 2014 ... www vmunix: [118396.260211] CPU: 1 PID: 0 Comm: swapper/1 Tainted: G C O 3.13-1-686-pae #1 Debian 3.13.5-1 Message from syslogd@www at Fri Mar 21 14:29:10 2014 ... www vmunix: [118396.260214] Hardware name: System manufacturer P5E-VM HDMI/P5E-VM HDMI, BIOS 0405 12/17/2007 Message from syslogd@www at Fri Mar 21 14:29:10 2014 ... www vmunix: [118396.260216] task: f7494da0 ti: f749c000 task.ti: f749c000 Message from syslogd@www at Fri Mar 21 14:29:10 2014 ... www vmunix: [118396.260233] Stack: Message from syslogd@www at Fri Mar 21 14:29:10 2014 ... www vmunix: [118396.260250] Call Trace: Message from syslogd@www at Fri Mar 21 14:29:10 2014 ... www vmunix: [118396.260268] Code: 00 00 8d bc 27 00 00 00 00 fa c3 8d b4 26 00 00 00 00 8d bc 27 00 00 00 00 fb c3 8d b4 26 00 00 00 00 8d bc 27 00 00 00 00 fb f4 <c3> 8d b6 00 00 00 00 8d bc 27 00 00 00 00 f4 c3 8d b4 26 00 00 Content of syslog: Mar 21 14:23:53 www ddclient[3535]: WARNING: file /etc/ddclient.conf, line 8: Invalid Value for keyword 'login' = '' Mar 21 14:26:50 www vmunix: [118276.128002] [sched_delayed] sched: RT throttling activated Mar 21 14:28:50 www vmunix: [118396.260001] INFO: rcu_sched self-detected stall on CPU { 0} (t=5250 jiffies g=2105139 c=2105138 q=2179) Mar 21 14:28:50 www vmunix: [118396.260001] sending NMI to all CPUs: Mar 21 14:28:50 www vmunix: [118396.260001] NMI backtrace for cpu 0 Mar 21 14:29:10 www syslogd: /dev/:0: No such file or directory Mar 21 14:29:10 www syslogd: /dev/:1: No such file or directory Mar 21 14:29:10 www vmunix: [118396.260001] CPU: 0 PID: 29 Comm: kswapd0 Tainted: G C O 3.13-1-686-pae #1 Debian 3.13.5-1 Mar 21 14:29:10 www syslogd: /dev/:0: No such file or directory Mar 21 14:29:10 www syslogd: /dev/:1: No such file or directory Mar 21 14:29:10 www vmunix: [118396.260001] Hardware name: System manufacturer P5E-VM HDMI/P5E-VM HDMI, BIOS 0405 12/17/2007 Mar 21 14:29:10 www syslogd: /dev/:0: No such file or directory Mar 21 14:29:10 www syslogd: /dev/:1: No such file or directory Mar 21 14:29:10 www vmunix: [118396.260001] task: f75344a0 ti: f76d6000 task.ti: f76d6000 Mar 21 14:29:10 www vmunix: [118396.260001] EIP: 0060:[<c122173a>] EFLAGS: 00000006 CPU: 0 Mar 21 14:29:10 www vmunix: [118396.260001] EIP is at __const_udelay+0xa/0x20 Mar 21 14:29:10 www vmunix: [118396.260001] EAX: 01062560 EBX: 00002710 ECX: fffff000 EDX: 00a30dac Mar 21 14:29:10 www vmunix: [118396.260001] ESI: c1576440 EDI: c1576440 EBP: 00000000 ESP: f76d7b7c Mar 21 14:29:10 www vmunix: [118396.260001] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 Mar 21 14:29:10 www vmunix: [118396.260001] CR0: 8005003b CR2: b6930d40 CR3: 2c03a000 CR4: 000007f0 Mar 21 14:29:10 www syslogd: /dev/:0: No such file or directory Mar 21 14:29:10 www syslogd: /dev/:1: No such file or directory Mar 21 14:29:10 www vmunix: [118396.260001] Stack: Mar 21 14:29:10 www vmunix: [118396.260001] c10392ed c14cccc9 f79b7840 c109a39a c14dad94 00001482 00201f33 00201f32 Mar 21 14:29:10 www vmunix: [118396.260001] 00000883 00006bae f79b7840 c1576440 c15b31ac 00000000 00000000 00000082 Mar 21 14:29:10 www vmunix: [118396.260001] f75344a0 00000000 00000000 00006bae c1059044 f76d7ca0 f76d7ca0 47052501 Mar 21 14:29:10 www syslogd: /dev/:0: No such file or directory Mar 21 14:29:10 www syslogd: /dev/:1: No such file or directory Mar 21 14:29:10 www vmunix: [118396.260001] Call Trace: Mar 21 14:29:10 www vmunix: [118396.260001] [<c10392ed>] ?
