Hello,
I am testing current sh-2.6.git on SH7709 based hp6xx,
using earlyprintk as Paul suggested me.
When booting, kernel shows an
Unable to handle kernel NULL pointer dereference at virtual address 00000000
and then
Kernel panic - not syncing: Fatal exception in interrupt
I built using arch/sh/configs/hp6xx_defconfig, and enabling
Verbose BUG() reporting and KALLSYMS_ALL as well.
This is the log :

Is there some .config option that I can use to go further?
By the way, I have built the kernel using a new toolchain for me,
(from Sourcery G++). Could it be the problem?
My old gcc-3.4.4-glibc-2.3.5 toolchain was always good for
kernel building, but I get compilation errors with current sh-2.6.git tree
(the compilation of linus git with the 3.4.4 gcc toolchain goes
well though).
Thanks in advance.

Can you boot this with ignore_loglevel on the command line also please,
it would be helpful to see what the sparse IRQ mapping looks like.

Based on this it would seem that you are entering the kernel with pending
timer IRQs and are racing against the clockevent setup, as no one has set
up the event handler yet. Try this:

If your patch is applied then I need to check why X does not run,
but that is another story.
If your patch is not going to mainline, then please, let me know
what should be done to continue fixing the original issue.
Thanks.

It would seem that the clock framework still needs a bit of work for this
CPU..

Good to see that sparseirq works as advertized here too.
