strange "process locking" behaviour with 6.0_BETA2

Hi,

Since I'm using NetBSD 6.0_BETA2 in my ${DAYJOB} workstation, I witness
weird behaviour every 24h or so.

While the whole system works (base X11, Xfce, DRI/DRM/3D radeon), for an
unknown reason, some processes will just stuck. For example, I had this
issue while building multimedia/mplayer, no CPU usage, no kernel message,
just stuck, like an I/O wait.
Today it happened with Gimp, when saving an image, gimp just hanged, no
way to kill it neither -15 nor -9, ps(1) show that the process is in 'DE'
state.

FYI, this is how my filesystems are mounted:

/dev/wd0a on / type ffs (log, local)
/dev/wd0e on /usr type ffs (log, local)
/dev/wd0f on /home type ffs (log, local)

I didn't find any opened PR about this, does this behaviour rings a bell
to anyone? I'll try to mount !root in async,noatime mode and see how it
behaves.

Thanks,
