 Posted: Sat Nov 25, 2006 2:53 am Post subject: kernel 2.6.17 patch to 2.6.18.2 possible? |
 |
|
Hello, all?
I have tried to upgrade my kernel from 2.6.17 to 2.6.18.2 using the commands patch p1 > patch-2.6.18.2. When I went through the motions, I said yes along the way. But after my system not boot properly(it loads the modules and other items but hults), I recieve an error that states "depscan.sh invalid 'to'". i tried to look at the depscan file but I did not see any errors (not that i know exactly what I was looking for). However, I was search these forums (googled aswell) and no one else had the exact same problem. One last thing was I supossed to some how "make" the patch, to install it?
p.s I have posted my patch-2.6.17.2 .rej & .orig file. are my files too long? I thought about just posting the "+" & "-" from he files.
any help would be app.
thanks Jason.
