Synopsis: PS/2 keyboard problems when NFS server under load

State-Changed-From-To: open->feedback
State-Changed-By: brooks
State-Changed-When: Mon Nov 1 21:50:46 GMT 2004
State-Changed-Why: 
Looking at the dmesg, I'm guessing you're probably writting to da1, the
USB disk.  If so I'm not too supprised you're seeing problems since the
USB system has serious latency problems in some cases.  Could you try
writing a file to which every drive you are using with a command like:

dd if=/dev/zero of=/path/to/file/on/drive

I'm curiously to know if that causes the same problems.  If so, we know
it's not NFS, if not it may or may not be (NFS could be pushing the
system over the edge if the root cause is elsewhere).
