Kernel 2.6.17.1 starts hangs after Data machine check in kernel mode.

[alayrac christophe]

Hi all,

I work in parallel on Linux 2.6.17.1 and 2.6.18.1 on ML403.

I've compiled 2.6.17.1 Kernel with TEMAC (V3) and without sysace, the
kernel starts and hangs after

Does some have any idea to solve the problem?
