Yes ... tried J6 on 2.4.18-pre4. If you want the garbled panic, it's attatched
below. What you're doing in J6 certainly looks different, but appears not
to be correct still. I'll look at it some more, and try to send you a patch
against J6 today.
On the upside, the perfomance of the your J4 patch with the added fix I
sent yesterday seems to be a great improvment - before I was getting
about 16% of my total system time spent in default_idle on a
make -j16 bzImage. Now it's 0% ... we're actually feeding those CPUs ;-)
Kernel compile time is under a minute (56s) for the first time ever on the
8 way ... more figures later.
