RE: [Linux-ia64] Problems building "2.4.0-test9" kernel source on /for IA-64

Creating a new and "virgin" Kernel source tree with the base
"linux-2.4.0-test9" tar-ball and apply
"linux-2.4.0-test9-ia64-001004.diff.gz" on top of it worked (ie no "patch"
pbs/errors at all) and finally allowed me to build a bootable + reliable
Kernel.

But this again looks to me as a possible improvement required with the
Kernel distribs+patching process which appear to require an un-touched
source tree receiving the base version and any further patches, in parrallel
of a second one used for builds and config. changes and to be kept in-sync
....

Bruno.
