Hi all,
I'm porting uClinux on a new architecture and I have reached the step of
init_process creation. When 'init()' function is called (init/main.c),
After checking a trace, the process 'kthread' is also created, but after
that the system enters in Panic.
It seems to be the following BUG_ON which is responsible for the problem:
BUG_ON(!PageSlab(page));
If I understand correctly, PageSlab return the value of the bit defined
by PG_slab (i.e number 7).
So it seems that 'page' is not contained in a slab. Am I right?
If so, what could be the problem?
Thanks in advance.
