Dear all,

Recently, I get the source code on the ubi-2.6.git tree. I compiled
the kernel on x86-32 arch and erverything is ok,but on x86-64,I met
some problems as follows
Environment
operation system:Red hat Enterprise Server 4.3(kernel 2.6.19 including
the UBI,gcc 3.5)
hardware:x86-64

Command
[linux-ubi$] modprobe nandsim second_id_byte=0x36
[linux-ubi$] modprobe ubi mtd=0

the result in the /var/log/messages

I think it's not the problem of the source code . I am not sure if it
is caused by the gcc version or the setting of configure options of
kernel on the x86-64 or something else?

Is anyone who met this kind of problem? Please could you tell me how
to deal with it,thanks a lot!

Your quick reply will be highly appreciated.

Best regards,
shiner
