I'm not sure which pool it is, I will attempt to find out.
At first I thought it was related to NFS, but recent crashes have led me
to believe otherwise. The one commonality is that it only seems to
happen during high disk activity. (Extracting a tarball or doing a
/sbin/restore). Another commonality seems to be that the pagedaemon
kernel thread and the (tar/extract) is runnable in the post-mortem "ps".
One unique thing is that this board has relatively little SDRAM (32MB), so
memory pressure is tight.
