Package: binutils-gold
Version: 2.21.0.20110302-1
Severity: important
Tags: upstream
Hello. I installed binutils-gold this morning (alongside the recent gcc 4.5
upgrade), and set about compiling a new 2.6.37.3 kernel (I can attach the
..config if you think there's anything relevant there). It linked and booted
fine. I then built the 260.19.44 NVIDIA kernel module, which similarly linked
and loaded without problems. Upon starting X, however, I get nothing but an
unzappable black screen. This extended back over several versions of the
driver, and to pristine 2.6.37. Removing binutils-gold and rebuilding 2.6.37.3
+ 260.19.44 generated wholly working objects.
Let me know what I can provide to assist. Thanks!

I tried to debug this issue earlier this year and found the module
produced by ld.gold a bit "smaller", missing a few relocation targets in
the .rodata section, probably due to "duplicate constant elimination".
I assume it's an upstream bug of misusing some values declared as
constant for r/w variables, so duplicate elimination causes different
variables to clash by using the same memory location.
I've been working around this problem by explicitly linking with ld.bfd
since then (kernel module source is patched).
