Folks,
twice now in the last 2 days when I have sat in front of my PC I
have found the following message on the screen:
Kernel not configured for semaphores (System V IPC). Not using udev
synchronization code.
Halting.
Since I have not modified my kernel from what I downloaded when I did
the most recent update I don't understand why this message is
appearing. Both times it occurred during the night because I find it
first thing in the morning.
Anyone have any idea what is causing this message to appear?
This is probably something else other than the kernel that has a bug.
You can check if your kernel has semaphores set by going into /boot and
running
grep -i -e 'IPC' [config file for your running kernel]
It should show something like
CONFIG_SYSVIPC=y
CONFIG_SYSVIPC_SYSCTL=y
CONFIG_IPC_NS=y
My suspicion would fall on systemd as a cause for your problem. But
that's just a guess based on the error message, I haven't actually
checked for the error message in the source.
