Nothing directly. > Closest thing is this: System.map is a list of function start addresses. Typically, functions don't crash at their very first instructions, this is why you don't see "exact" matches. > 8810d9b0 t ip22zilog_maybe_update_regs > 8810d9fc t ip22zilog_receive_chars This is epc (+0x20). > 8810dd18 t ip22zilog_status_handle > 8810def0 t ip22zilog_transmit_chars > 8810e0e0 t ip22zilog_interrupt ...and this is ra. > 8810e26c t ip22zilog_tx_empty >From my fading MIPS knowledge, ip22zilog_interrupt called ip22zilog_receive_chars and the later one crashed. Now, use objdump and create a disassembly dump of the object file that contains the IP22 Zilog stuff. There, find the part that's 0x20 bytes away from the start of ip22zilog_receive_chars. Now you know the cause of this oops. From here, try to figure out the reason for it...
