[Kerne] problemi ricompilazione per acpi

[dona]

Ciao io uso debian sid ed ho su un kernel 2.4.20 proveniente da kernel.org . Appena scompattato da tar ho applicato in sequenza le patch :
acpi-20021212-2.4.20.diff.gz
patch-acpi-acpi20021212-swsusp19.gz
senza riscontrare nessun problema.
Con cio' ho ricompilato e dopo un po' ricevo il seguente messaggio di errore

sutils.c nswalk.c nsxfeval.c nsxfname.c nsxfobj.c > .depend
make[8]: Leaving directory `/usr/src/kernel-source-2.4.20/drivers/acpi/namespace'
