Kernel panic - not syncing: Kernel Fault
  <0>Rebooting in 120 seconds..

this time it panics after 138 loop only?

I well reach to build a kernel with CONFIG_DEBUG_RWLOCK
<http://lists.parisc-linux.org/pipermail/parisc-linux/2004-December/025337.html>

but failed to boot.

Don't you think it could help to debug this pb?

Thanks for all,
	Joel
