That said, let's talk about this... I built the latest kernel using linux-next as well as the torvalds build git last night. Here are the commands I used (in case you see any problems). git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git git remote add linux-next git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git cd linux git remote add linux-next git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git git fetch linux-next git fetch --tags linux-next cp /boot/config-4.3.4-300.fc23.x86_64 .config make oldconfig make -j8 bzImage; make -j8 modules; make -j8 modules_install; make -j8 install This resulted in a functioning 4.5rc5+ kernel. a matter of hours later the storage once again disappeared from my ESXi hosts. I understand there may be things I need to tweak on my hosts, but should those things cause LIO to stop responding from the target server? It's back to acting the same exact way as before (with the target-pending/4.4-stable from a month ago), I can't stop the service or kill the process. # uname -a Linux dracofiler.home.lan 4.5.0-rc5+ #2 SMP Sat Feb 27 15:22:25 EST 2016 x86_64 x86_64 x86_64 GNU/Linux # ps aux | grep target root 2531 0.2 0.0 214848 15500 ? Ds 11:48 0:00 /usr/bin/python3 /usr/bin/targetctl clear This is what I mean by "crashes", targetctl hangs here and there is absolutely nothing I've been able to do to get it to start responding again other than rebooting.
