Subject: 3.1-rc6 boot problem reason searching

With M586 it also boots.

Enclosed is the dmesg , if of any importance   (ignore 
that the kernel is named -i486, this is only because I 
don't want to rename everything, hoping that soon M486 
returns to work).

Below is also the diff which config's are changed 
implicitely on changing from M486 to M586 .




Thus, the problem is between M486 and M586 ,  compiled 
with 486 it don't boot, but compiled for 586 it boots.

Alias, M686 runs the whole day without any other problems.

You can suggest me now a next config to try out for better 
find the reason for the problem.
