That's fantastic!
This brings us one big step further to being able to build a real
debian-unstable-installer boot CD.
I'm still hoping the C8000 patches I pushed for inclusion into 3.11
will then
show up in stable 3.10 series soon as well. If that happens we will
have a kernel
which should boot on all machines - including the c8000.
I have bootstrap tested the linux-image-3.10-1-parisc64-
smp_3.10.3-1_hppa.deb package. We'll
have to see if 3.10 will be the Debian choice for the next release.
As I mentioned in private, I have found that flush_cache_all() is the
principal problem causing random
segmentation faults on SMP systems.
That would tend to indicate the architectural flush code is wrong: it
isn't flushing all as it should be.
That thought had occurred to me. It's also possible that it doesn't
work
properly with the L3 added in the PA8800/PA8900 systems.
What seems to work is flushing all the user mappings.
I should note that I have also seen corruption of space register %sr1
(added checks in the routines that use pa_memcpy). I think the only
way that can happen is kernel stack corruption. Probably, this is also
caused by flush_cache_all. I know this issue has been around for
a long time.
I'll look at the flush code again.
