rd I have experienced kernel hangs w/ -current snapshots on Athlon 64 X2
rd and Sempron boxes. Both GENERIC and GENERIC.MP snapshots exhibit the
rd hang. Once hung, the boxes don't respond to pings; however, keyboard
rd LEDs toggle as expected and I can enter ddb from the keyboard.
rd kernel/5777 [1] has the full problem report including dmesgs and ddb
rd logs. The hang is reproducible by building the eclipse-sdk port.
rd This problem has developed fairly recently (within the past month or
rd so).
rd A similar box (w/ Opteron 165) runs -current i386 GENERIC.MP snapshots
rd and is able to do the same port builds without hanging. It seems the
rd forementioned kernel hang doesn't affect the i386 variant.
rd I would be happy to provide additional information that would help
rd analyze and resolve the problem.

I've now had the kernel hang occur on 3 different amd64 boxes. (no
ping response. top freezes. Only kb LEDs work. ddb can be entered
from the keyboard.)
Unfortunately, this last hang occured on a box without a serial port
so I have no ddb info to add to the above problem report. I do have
crash dumps from this last hang.
The hang is reproducible by building the eclipse-sdk port on -current.
It does appear to require enough memory load to swap. On this last
box, it wouldn't hang until I artificially added another 750MB load
(see below).
From the associated ddb ps listings (several sessions), I see several
processes WAITing on flt_noram[135]. Amongst those sessions, javadoc
usually shows up WAITing on flt_noram5. I have no idea whether that
is relevant to the hang but it does seem to form a pattern.
I'd appreciate help to further analyze the problem report and correct
the problem.
FWIW, it seems odd that no other reports of (or replies about)
this problem have occurred. Are my 3 boxes the only ones that hang?
Here's the simpleminded memory loader:
perl -e '$n=1024*1024;for($i=0;$i750;$i++) { $mem[$i]=z x $n; }; ;'
As previously mentioned, kernel/5777 contains the full report
including dmesgs. I've appended the 3 dmesgs here as well.
