Hi David,

Sorry to say, but your commit d406c9ae84d6ef12c55a41c97c34266b2eb7ed31 makes my TX49xx (Toshiba RISC mipsel) based system unusable.

The kernel boots fine until the stage:
   Freeing unused kernel memory: 140k freed
and then stops.
Some of our LEDS are updated as supposed, so a part of the kernel should be running.

Reverting your commit makes the latest 2.4.37.4 kernel usable again.
Do you have an idea what might go wrong?


I'm sorry, I can't think of anything.

I would look in copy_thread and the kthread spawning code. Does TX49xx have custom versions of these?
