Hi,
while debugging arcboot and some interesting crashes related to caching
etc i found a disassemble bug in gdb
0x88166b58 <probe_scache+188>: mtc0 zero,gp
0x88166b5c <probe_scache+192>: nop
0x88166b60 <probe_scache+196>: mtc0 zero,sp
0x88166b64 <probe_scache+200>: nop
mtc0/mfc0 do not address cpu registers but CP0 registers. The decoding
as "gp" or "sp" is not correct. These are "TagLo" and "TagHi".
If somebody has an idea why the kernel crashes when writing to
TagHi - Speak up ... This only seems to happen sometimes not always.
