Subject: machine check on mpc8343

All,

we're running 2.6.27 on a MPC8343 cpu - nothing special so far.

With heavy system load I get a machine check exception on some boards
within 1-3 days leading to immediate reset.

U-Boot blames "Check Stop" causing the reset - I can also observe the
check_stop_out signal of the CPU being asserted.

Dumping the kernel's "__log_buf" location within U-Boot shows the kernel
log buffer without any error.

Is there a reasonable/default way to get more Infos out of the kernel
before he dies ?

A solution other than "write your own ppc_md.machine_check_exception" is
preferred ;-)

regards,
Andre
