Hi well the kernel upgrade worked except now my wireless stopped 
working. In addition the patch to the mouse driver gave exactly the same 
errors as under  10.04 2.6.32-24-generic. How do I revert the kernel 
back to 2.6.32-24-generic so I can get wireless back?

thanks, Simon

p.s. FYI. When I first upgraded to 10.04 I had to go on to a wired 
conenction and do an update to get the latest patches to get wireless to 
work which I did not have to do with 9.04.
