Kernel Stack vs User Mode Stack
Hi,
I am new to the linux kernel development area. I want to know what is the difference between kernel mode stack and user mode stack? Does each process has a user mode stack and a kernel mode stack?? Or Each process has a user mode stack and there is only one kernel mode stack that is shared by all processes in the kernel mode?

I have a multithreaded usermode program(actually a daemon) which is in hanged state.
To debug it I tried attaching the process to gdb, but the gdb hangs.
gstack also gets hanged.
I peeped into the proc file system and saw the process to be in sleeping state.

glloadname
GLLOADNAME(3G) GLLOADNAME(3G)
NAME
glLoadName - load a name onto the name stack
C SPECIFICATION
void glLoadName( GLuint name )
PARAMETERS
name Specifies a name that will replace the top value on the name stack.
DESCRIPTION
The name stack is used during selection mode to allow sets of rendering commands to be uniquely identified. It consists of an ordered set
of unsigned integers. glLoadName causes name to replace the value on the top of the name stack, which is initially empty.
The name stack is always empty while the render mode is not GL_SELECT. Calls to glLoadName while the render mode is not GL_SELECT are
ignored.
ERRORS
GL_INVALID_OPERATION is generated if glLoadName is called while the name stack is empty.
GL_INVALID_OPERATION is generated if glLoadName is executed between the execution of glBegin and the corresponding execution of glEnd.
ASSOCIATED GETS
glGet with argument GL_NAME_STACK_DEPTH
glGet with argument GL_MAX_NAME_STACK_DEPTH
