darner sometimes freezes during periodic job

[Pierre Abbat]

Darner froze a few minutes ago and I had to reboot it with the power button. 
It did the same thing several nights ago. I was not running top, but I think 
it was running hammer. It runs version 3.5.0.25. Zyxomma doesn't do this; it 
runs version 3.4.1. I don't get a dump file, a kernel panic, or any other 
indication of what happened except maybe "busy page found in cache". Is this a 
known bug, and what should I do?
