[18:16] <hemin> Hi, I modified the kernel source.. and now I want to recompile the kernel.. so when i go to /usr/src/linux/kernel and do make it doesnt work.. it says "No rule to make target `FORCE', needed by `/config_data.gz'.  Stop." .. Do I have to recompile the whole kernel source again just to include a small change??? How can I do it faster?
[18:49] <quentusrex_> Anyone have advice on how to track down the cause of high load on a fresh ubuntu server caused by ksoftirqd processes?
[18:50] <quentusrex_> I have two servers with identical hardware, both freshly installed ubuntu 11.04 server 64 bit, fully updated and only one of them is having this problem.
[18:50] <quentusrex_> After a wipe and reinstall the problem still exists, on the same server.

[19:34] <quentusrex_> I am testing the pre-proposed kernel now on the machine. I will report back if that resolves the issue. Also, on the 2.6.38-10 kernel adding noapic to boot options does nothing.
[19:34] <quentusrex_> in particular I'm testing: linux-image-2.6.38-11-server_2.6.38-11.47pre201107220904_amd64.deb
[19:49] <quentusrex_> That version suffers from the same problem.
