Description Peter Collinson 2002-11-08 14:55:54 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (Win98; U)

Description of problem:
The kernel build fails when making modules. It seems that the file:
include/linux/modules/ksyms.ver is saying:

#define loops_per_jiffy _set_ver(loops_per_jiffy)

and loops_per_jiffy is a member of a structure 
	struct cpuinfo_x86
that is broken by this definition. The structure entry becomes
        unsigned long loops_per_jiffy_R_ver_str(ba497f13);
which isn't legal.

Since the default for the config program is to enable this flag, it causes great confusion with Linux novices
like me - who really expect that kernels from Redhat should compile..

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Start with a fresh kernel and no .config file
2. Run make config and select nothing - simply save the file
3 make clean
4 make dep
5 make bzImage
6 make modules


Actual Results:  Compilation dies  - in my case in module - cdrom.c. Sorry I have lost the actual results since I found the workaround
for the problem.

Expected Results:  The kernel should compile.
