Subject: [PATCH] Time runs too quickly on Cobalt
Date: Fri, 06 Oct 2006 16:54:54 +0100	[thread overview]
Message-ID: <45267C4E.8090101@talk21.com> (raw)

If I build a kernel with HZ==250 then time runs about 4 four times too 
quickly on my Cobalt RaQ2.

The following patch seems to fix it but I'm not sure this is the correct 
thing to do.
