my suggestion was more due to the glibc bug flagged by Hal.  If this issue surfaced
with 2.6.26, I might try to go back one or two versions, that's why I mentioned going
back to a previous patch.

fair enough.  I just wanted to avoid having both an unstable kernel and unstable PPS code...
But I guess that this is what testing is about!

recompiling just now, I can test from remote and will let you know.  But compiling a kernel on
a Pentium MMX 200 might take a while!  Luckily this is just minor diffs, but if I need to recompile
from scratch I open the box and connect the HD to faster machine to recomiple, then move the
HD back to the MMX! ;-)
