Hi all,
Since Peter Holm's stress2 suite seems to very reliably crash an
rpi2 running -CURRENT it seemed worthwhile to try collecting a
core dump in the hope it might shed some light visible to others
(certainly not me!) on the cause. The intent is to add it to the
collection at www.zefox.net/~fbsd/rpi2/crashes. For some reason
crash dumps aren't being recovered.....
/etc/defaults/rc.conf contains:
dumpdev="AUTO" # Device to crashdump to (device name, AUTO, or NO).
dumpdir="/var/crash" # Directory where crash dumps are to be stored
savecore_flags="-m 10" # Used if dumpdev is enabled above, and present.
# By default, only the 10 most recent kernel dumps
# are saved.
crashinfo_enable="YES" # Automatically generate crash dump summary.
crashinfo_program="/usr/sbin/crashinfo" # Script to generate crash dump summary.
There are no overriding directives in /etc/rc.conf, but the only thing
found in /var/crash is:
root@www:/usr/src # ls -l /var/crash
total 4
-rw-r--r-- 1 root wheel 5 Jun 11 08:27 minfree
root@www:/usr/src # more /var/crash/minfree
2048
Permissions on /var/crash are:
drwxr-x--- 2 root wheel 512 Jun 11 08:27 crash
which seem acceptable if a little insecure.
There is a physical swap partition in /etc/fstab, thus:
/dev/da0p2 none swap sw 0 0
with a size of
8388648 6291456 2 freebsd-swap (3.0G)
It looks as if all the pieces are in place, but core dumps aren't being
recovered....what am I doing wrong?
Thanks for reading,
bob prohaska
