I am unable to run UML mode (i386) under 2.6.12: the execution gives the
following messages.

By the way, the output beyond the first three lines has to be printed
out after a hack of printk(), as the latter usually failed to print out
anything.
The kernel is compiled with a ported config from 2.6.10-um, and is run
under exactly the same condition as the 2.6.10 counterpart which works
fine. The host is under Linux-2.4.31.
