While stress testing 2.6.12-rc2 on an HP DL145 I get processes stuck
in D state after some time.
This machine is a dual Opteron 248 with 2GB (ECC) on one node (the
other node has no RAM modules plugged in, since this board works only
with pairs).
I was using stress (http://weather.ou.edu/~apw/projects/stress/) with
the following command line:
stress -v -c 20 -i 12 -m 10 -d 20

Unfortunately the system Oopsed in the middle of dumping the tasks, but from what I can see I'm tempted to think that this might be related to the MD code. md2_raid1 is blocked on D state and, although not shown on the dump, I know from ps command that md0_raid1 (the swap partition) was also on D state (along with the stress processes which are responsible for hogging memory, and top and df). There were about 200MB swapped out, but the swap partition size is 1GB.
