I tried that. 2.4.16-pristine + CML2, no existing .config or
config.out. Add -D$(ARCHSYMBOL) to the oldconfig command. make
oldconfig, same problem.
python2 -O scripts/cmlconfigure.py -t -DX86 -B 2.4.16 -I config.out rules.out
Side effects:
ISA=y (deduced from X86)
X86=y would have violated these requirements:
"config.out", line 289: bad token `SCSI_DEBUG_QUEUES' while expecting symbol.
File load violated these constraints:
(((FB == n) and X86) implies ((FONT_8x8 == y) and (FONT_8x16 == y)))
Attempting recovery from invalid configuration:
Symbol FB forced to n during recovery attempt.
Symbol X86 forced to n during recovery attempt.
Symbol FONT_8x8 forced to n during recovery attempt.
Symbol FONT_8x16 forced to n during recovery attempt.
Undoing file loads, recovery failed these constraints:
(SMP implies (X86 or (PPC or (ALPHA_SABLE or (ALPHA_RAWHIDE or (ALPHA_DP264 or
(ALPHA_WILDFIRE or (ALPHA_TITAN or (ALPHA_GENERIC or (SPARC32 or (MIPS64 or
ARCH_S390)))))))))))
The first question it asks is "arch: Processor type"?

After installing cml2 1.9.5 on 2.4.16 pristine and applying this patch
to get around the first problem. python2-2.1-2 from RH.
