Has anyone had problems with hardware breakpoints from external
debuggers? I'm using RISCWatch, which sets DBCR0 and IAC1 for me (yes
I've verified that). I'm then using 'echo > /proc/sys' to invoke my
code. However by the time I get to my sysctl proc handler, DBCR0 has
been reset from 0x80810000 to 0x00010000, hence IAC1 is ignored.

I don't see much use of DBCR0, other than initialization and then save
during exception prologs and then restore during task restore. Can
anyone point me to where it might be reset?
