insmod fails HardHat Linux on a Walnut eval kit

insmod fails HardHat Linux on a Walnut eval kit

[Ramzi Maalouf]

hello -
	I created a hello world module, cross-compiled, and then ran insmod.
Insmod causes a segmentation fault.  I ran the strace and this is the
output.  Has anybody has any similiar problems, what did you do ?

Are you using the target file system from the "CDK 1.2 IBM PowerPC 405GP
Targets" or another one (and if so, which one)?

Which kernel version are you using?

Rev C or Rev D Walnut?

Thanks,

Frank
