2.4.7ac9,10 compile error

[Holzrichter, Bruce]

Hey guys,

I am trying to install 2.4.7 on my Ultra 5, and I am running into some
problems.  Got some errors compiling a sound module to start so I updated to
2.4.7ac9 and tried again, but got the following error.  I also updated to
2.4.7ac10 that just came out, and got the same error on compile.  Any ideas
where I am going wrong?

Error:
In file included from sched.c:26:

/usr/src/linux-2.4.7/include/linux/irq.h:61: asm/hw_irq.h: No such file or
directory

make[2]: *** [sched.o] Error 1
