Kernel stack overflow in process xxxx

Kernel stack overflow in process xxxx

[jay_chen]

Hello all:

I am using mpc8548 and, kernel 2.6.14.5.
Recently, my system encounter "Kernel stack overflow in process xxxx"
problem.
How to increase the kernel stack size?
I try to modify THREAD_SIZE in thread_info.h, but my system seems couldn't
boot up anymore!

//#define THREAD_SIZE		8192	/* 2 pages */
#define THREAD_SIZE		  16384	/* 4 pages */

Thanks in advance for any kind of advice.

By the way, is there any skill/tool to avoid/detect/check this kind of
problem?

did you try:

Kernel hacking  --->
  ...
  [*] Kernel debugging
  ...
  [*] Check for stack overflows
  [*] Stack utilization instrumentation

the last one depends on SysRq though.

In any case it would be interesting to know if these tools can help find
problems of this kind - so if it does not help - pleas let me/us know.
