[ELDK] Recent valgrind on libc 2.6, ELDK 4.2 (ppc_4xx) ?

Can you give more details on why this fails?  I was under the impression
that this should work pretty flawlessly, but I haven;t checked lately.

I agree.  You should concentrate on getting a recent version to work.
So maybe if you show us more details on what fails, we can help.

2) interrupt handler runs a long time:    I'm sure we still have some of those
especially in the archaelogical corners of drivers/* and in the creative space
of the embedded  "oh, I don't know why but it works" departement.  That's code
which needs to be fixed anyway.                            -- Thomas Gleixner
