Subject: machine check on mpc8343
Date: Wed, 26 Nov 2008 18:39:05 +0100 [thread overview]
Message-ID: <492D89B9.1040708@matrix-vision.de> (raw)
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
