To have a bit of a work around for the Intel Meltdown bug (yes, no
Spectre), I wanted to try out some AMD based CPUs.  So far so good using
a SuperMicro H11SSL-i.  A decent server board using an Epyc CPU.  All
the things you need and expect for a server grade MB

ipmi to provide remote management (SoL to BIOS and OS) and hardware
info.  The ipmi.ko driver works great with RELENG11.  This allows for
hardware watchdog support too.

amdtemp from CURRENT also works to provide cpu temp info, although
ipmitool does this as well.

Seems to sit at about 50W when idle and tops out at about 180W with 2
SSD drives and all cores busy.


Note, the bug in
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225584
and discussed in
https://reviews.freebsd.org/D14347
manifests itself fairly readily. However, the patch fixes the problem

Attached is some dmesg info for the curious.  Seems like a decent board
for FreeBSD and we are going to start deploying in a couple of spots
once we do some more burn in and testing.
