Thanks to all of you working on that.

I currently do not have problems with glibc, at least I don't see any (Gentoo, 
using their 2.14 version). What I see are problems in binutils, although 
AFAICT those are not really HPPA-specific. One easy test is to build a recent 
version of CMake: if you specify no compiler flags bootstrapping will work, as 
I inserted -Wl,--unique=.text.* into the LDFLAGS there. But if you pass -O2 if 
will not build (binutils 2.23.[12]). If you remove the linker flag it will not 
work without -O2. I can't build newer kernels for my C8000 with frame pointers 
as it will crash ld with a NULL deref somewhere, older kernels work (probably 
smaller).

But otherwise my machine became pretty stable in the last time, that is really 
good ;)

Greetings,

Eike
