I noticed a problem where my system would hard hang when powerd was
enabled with no changes to the powerd flags in rc.conf. Yesterday, I
tracked the problem down to powerd's Adaptive mode causing the hard
hang.
I first noticed the problem, when I was trying to transfer /usr/ports,
/usr/src and /home/ncvs via nfs to my HP Pavilion dv8xxx laptop.
Later I found that I could cause the system to hang when extracting
cvs-cur CTMs.
mkdir /home/ncvs
cd /home/ncvs
ctm /mnt/CTM/*.gz
Note: the CTM directory contaings:
cvs-cur.12200xEmpty.gz
cvs-cur.12201.gz thru cvs-cur.12433.gz
If I disabled powerd, or changed the powerd_flags to "-a maximum -b
minimum", then this system wouldn't hang when extracting the CTM
archives.
Attached are the dmesg output, kernel configuration, loader.conf,
rc.conf, and the output of powerd -v when the system would hang.
I built a debug kernel, but I couldn't break into the debugger with ctl-alt-esc.
Note: GENERIC.debug includes the default GENERIC configuration (hasn't
been modified).
The system is running FreeBSD 6.1-Stable/amd64
