This is probably a sysctl handler that is causing the reboot. You can

Each sysctl will be called in turn and the output is appended to
a file, but the file will forcibly written to the disk before the
next occurence.
Um ... it is my understanding sync(8) does not guarantee
pending i/o will be written before it returns, but merely requests
this happen irrespective of when it would normally occur.
An I mistaken?
Honestly I don't know, but I have do admit that the small paragraph in
the BUGS section of the sync(2) manpage is a little bit shivering:
BUGS
The sync() system call may return before the buffers are completely
flushed.
Can any enlightened person answer this?
