[Bug 219399] System panics after several hours of 14-threads-compilation orgies using poudriere on AMD Ryzen...

--- Comment #16 from Nils Beyer <nbe at renzel.net> ---
Sound loops are somewhat new to me - my music that is playing while using the
computer just stops - no sound artifacts at all.

Something else I've noticed are often messages in the poudriere logs like:

    error: unable to rename temporary '...' to output file '...': 'No such file
or directory'

I'm using tmpfs for the work directories. So I've reconstructed that for a
buildworld/buildkernel stress test:
--------------------------------------------------------------------------------------------
#!/bin/sh

trap "exit 1" 1 2 3

cd /usr/src
umount /usr/obj
mount -t tmpfs tmpfs /usr/obj

while [ 1 ]; do
        echo "`date` begin"
        BEG="`date +%s`"
        make -j20 buildworld buildkernel >/usr/obj/${BEG}.log 2>&1
        ERR="$?"
        echo "`date` end - errorcode ${ERR}"
        [ "${ERR}" != "0" ] && cp /usr/obj/${BEG}.log /usr/src/.
        rm /usr/obj/${BEG}.log
done
--------------------------------------------------------------------------------------------


And yes, I get these "unable to rename..." messages as well:
--------------------------------------------------------------------------------------------
1498777486.log:error: unable to rename temporary 'ofb_enc.pico-91eb399a' to
output file 'ofb_enc.pico': 'No such file or directory'
1498797284.log:error: unable to rename temporary
'CodeGen/MachineModuleInfo.o-f77c51a1' to output file
'CodeGen/MachineModuleInfo.o': 'No such file or directory'
1498806242.log:error: unable to rename temporary 'dsl_deleg.o-68764d23' to
output file 'dsl_deleg.o': 'No such file or directory'
1498807306.log:error: unable to rename temporary
'StaticAnalyzer/Frontend/ModelInjector.o-a246df8d' to output file
'StaticAnalyzer/Frontend/ModelInjector.o': 'No such file or directory'
--------------------------------------------------------------------------------------------

Maybe that is a good and quick indicator for something being wrong. Perhaps
somebody can try that, too, please?


As a side note, I've tried to set the RAM timings to something even, as I'm
using a 2133 MHz RAM; the default timings are CL15, and in the AMD forum's
thread here:

    https://community.amd.com/message/2805287

it is said that Ryzen has problems with odd timings. Unfortunately, no
improvements raising CL to 16...
