For now it seems 4.3.0-00063-gea2d67b and 4.3.0-08824-g7c623ca also 
survive for many hours. That is strange - I think I saw it earlier on 
v240 where I am currently testing (I have seen it multiple times on 
v240, only once or twice on v440).

Now I have also ran 4.4-rc8 on v440 for some hours and it seem to 
survive.

So I do not know how to reproduce the reboot at will :(

Nothing in ALOM console log history or in syslog.

v240 has 6G RAM, v440 has 8G.

Userland is Debian unstable, as it was as of July 25, 2015. gcc 4.9.3-2, 
binutils 2.25-10.

My usage pattern on all the machines was powering up the machine, doing
git pull && make -j4 && echo OK
where -j number corresponds to number of CPUs in the system. Maybe git 
pull created some memory pressure before?

ps shows I have running
init udevd dhclient uuidd rsyslogd atd cron irqbalance sshd exim4 ntpd 
getty + sshd,bash for my login session.

v440 also has /usr/bin/daemon /etc/init.d/mpt-statusd check_mpt

init is sysvinit on both machines.

irqbalance and ntpd are the only slightly suspicious ones for my eye, or 
i2c modules but these are only on v240.
