IBE Instruction fetch bus error. EBASE+0x180 EXL — 0x06 _general_exception_handler
Instruction
Validity
Exceptions
An instruction could not be completed because it
was not allowed to access the required resources
(Coprocessor Unusable) or was illegal (Reserved
Instruction). If both exceptions occur on the same
instruction, the Coprocessor Unusable Exception
takes priority over the Reserved Instruction
Exception.
EBASE+0x180 EXL — 0x0A or
0x0B
_general_exception_handler
Execute
Exception
An instruction-based exception occurred: Integer
overflow, trap, system call, breakpoint, floating
point, or DSP ASE state disabled exception.
EBASE+0x180 EXL — 0x08-0x0C _general_exception_handler
Tr Execution of a trap (when trap condition is true). EBASE+0x180 EXL — 0x0D _general_exception_handler
DDBL/DDBS EJTAG Data Address Break (address only) or
EJTAG data value break on store (address +
value).

AdEL Load address alignment error. User mode load
reference to kernel address.
EBASE+0x180 EXL — 0x04 _general_exception_handler
AdES Store address alignment error. User mode store to
kernel address.
EBASE+0x180 EXL — 0x05 _general_exception_handler
TLBL Load TLB miss or load TLB hit to page with V = 0. EBASE+0x180 EXL — 0x02 _general_exception_handler
TLBS Store TLB miss or store TLB hit to page with V = 0. EBASE+0x180 EXL — 0x03 _general_exception_handler
