Hi,

   I've recently nocied that update seems to be taking up too much CPU 
time according to top.

I'm running a kernel compiled today, with the vm_update.c patched
as announced in current-users today, and a SA110 CPU

  It varies from 6% when it's 'sleeping' for its 30 seconds to upto 30 or 
even 50% when it 'wakes up'. When it does wake up, the whole machine 
freezes for about a second (At least typing into this xterm does) and 
when it unfreezes, I often get the last key pressed repeated many times 
over. It also doesn't seem to register keypresses while frozen.

  Oh, another thing. I'm not actually doing anything to the filesystem at 
the mo, so syncing the disks isn't writing anything to them.

  I don't think this happened with kernels compiled  ~2 weeks ago.  

Has anyone else experienced this with the latest source?  Can anyone shed 
light on this?

  Are there any ramifications to running without update? (I'm using the 
machine mainly as an xterminal at the mo, i.e. not writing much to disk)

Ale.
