While inspecting the 2.4 cvs kernel, I saw that arch/mips/kernel/head.S does not have a .align for ejtag_debug_buffer -- just a ".fill 4". The alignment happens to be correct, I guess since it's the first .data segment item in the file, but anyone rearranging the code could trigger a misalignment, which causes an unaligned trap inside an exception... try debugging that one. (OK, I got lucky...) The 64 bit cvs kernel doesn't yet have this ejtag stuff in it. 2.5 looks the same as 2.4. -- greg
