Sorry, the first part of the conversation happened on IRC, my bad.
I was trying to figure out why I was seeing a problem that Joel had
reported before and no-one else was. Kyle got me to try a sid chroot,
and it didn't happen there. Eventually I narrowed down the difference
between a working kernel and a non-working one was whether I was using a
bleeding edge CVS snapshot, or whether I was using the released
binutils-2.17 package.
I'm not claiming I know where the bug is, but I wanted to know what the
change was that happened between a bootable kernel and a non-bootable
kernel.

Although when you're in the situation that RMS is telling you that
you're being too ideological about freedom, maybe, just maybe, it's
true.
