I see the following error running dmesg in my Linux running on a embedded board (Qualcomm RB5). The Linux is built using Yocto.
/ # dmesg
dmesg: klogctl: Operation not permitted
As you see, I'm running as root. I am also aware of the question here. But when I issue the solution given there I get the following error:
/ # echo 0 > /proc/sys/kernel/dmesg_restrict
sh: write error: Operation not permitted
Any idea how should I get around with it?

Im working on LFS, and I finished the process of compiling, and came to the part of entering the cheroot Environment, with the code provide.
But I’m getting this error:mesg: ttyname failed: no such device
How can I resolve this?
There is a mesg n command in you /root/.profile or so. Just comment it out or ensure it is run only if running on a tty with test -t 0 && mesg n.
I have 2 twin servers, with same hardware (Infiniband and Nvidia Tesla) and same OS (CentOS6.6, kernel and drivers).
On host1 everything is working fine as usual, while
on host2 I cannot run anymore this service, because I get this error:
[root#vega2 nvidia_peer_memory-1.0-0]# service nv_peer_mem start
starting... FATAL: Error inserting nv_peer_mem (/lib/modules/2.6.32-504.el6.x86_64/extra/nv_peer_mem.ko): Invalid module format
Failed to load nv_peer_mem
and dmesg says:
nv_p2p_dummy: exports duplicate symbol nvidia_p2p_free_page_table (owned by nvidia)
Note that host2 has been working fine for 2 months, until a rebooted it after summer holydays. :-(
What can be the cause of this error ? The main software component didn't change (kernel, Nvidia drivers, Mellanox drivers) and hardware is ok. I tried also to repeat the installation procedure, but I get stuck at module loading point:
[root#vega2 nvidia_peer_memory-1.0-0]# rpm -ivh /root/rpmbuild/RPMS/x86_64/nvidia_peer_memory-1.0-0.x86_64.rpm
Preparing... ########################################### [100%]

FATAL: Error inserting nv_peer_mem (/lib/modules/2.6.32-504.el6.x86_64/extra/nv_peer_mem.ko): Invalid module format
I found this post about two kernel modules exporting the same symbols, but why on host2 this second module is disturbing nv_peer_mem, while on host1 it does not ?
Here is the output of nm commands, exactly the same for both hosts.
[root#vega2 nvidia_peer_memory-1.0-0]# nm /lib/modules/2.6.32-504.el6.x86_64/kernel/drivers/video/nvidia.ko |grep nvidia_p2p_free_ page_table

This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the user guide chapter on the daemon at https://docs.gradle.org/2.10/userguide/gradle_daemon.html

the jvm version is 1.7.0_79

There's no space available in RAM. To fix go to /android-studio-dir/bin and edit studio.vmoptions and studio64.vmoptions to increment the -Xmx and to reserve more memory to Java. Note that the number of processes active may influence on that.
Probably, the /tmp location is full..
Found this somewhere..
Use df command
df
You should see an output with a line like this:
tmpfs 102400 102312 88 100% /tmp
So to change the size of the tmp file:
sudo mount -o remount,size=2G /tmp
Done! Now, It should work..
When I start the Cygwin shell in Windows XP, I get a stream of messages like this:
0 [main] -bash 2920 C:\cygwin\bin\bash.exe: *** fatal error - prefork: couldn't create pipe process trackerWin32 error 161
I get yet more messages whenever I run scripts and commands. The shell appears to work underneath the flood of errors, but it is very annoying.
Is there any way to find out what is causing this or to fix it?
