Hi,

I'm porting linux(2.6.31.6) to the Wintegra WINHDP2 = refrence board.

As a refrence I already have an old BSP from = Wintegra based on kernel 2.6.10.

During the kernel start up process I receive = following error:

One reason for this might be an incorrect CPU type setting in the kernel configuration resulting in the generation of such code.

Look at the preceding code -- the EXL bit has just been cleared (while executing handle_ri_int()) and the interrupt exception has been immediately taken, overwriting the EPC and Cause registers with what you can see above. So either the original RI exception happened earlier elsewhere, or there is something completely broken somewhere resulting in this misleading dump (like stack corruption resulting in a jump to handle_ri() or whatever). To figure out which is the case I'd suggest running the RI handler with interrupts disabled for debugging and see if the correct values from EPC and Cause are reported. If this runs correctly, then obviously the causing place of the RI exception has to be fixed, but also the interrupt exception handler has to be investigated to see why the values from EPC and Cause stored on the stack get corrupted. Otherwise the new symptoms will (hopefully) suggest what to do next.

Hi,

I'm porting linux(2.6.31.6) to the Wintegra WINHDP2 = refrence board.

As a refrence I already have an old BSP from = Wintegra based on kernel 2.6.10.

During the kernel start up process I receive = following error:

Reserved instruction in kernel = code[#1]:

Disabling lock debugging due to kernel = taint

Kernel panic - not syncing: Attempted to kill the = idle task!

Does anybody know where is the = problem?

I suspect, that the problem is in my interrupt = routine, because I receive this error as soon as the tick timer start's = up.

Ales
