But I could somehow not get the call trace and hence could not report the bug. I compiled the kernel with "CONFIG_FUNCTION_TRACE" and then I get undefined references on "early_printk". Is there something I am doing wrong in the kernel config or was there an additional patch to enable this support for MPC5200 ? I see more bugs when I run "stress" but I cant solve them or even report them, because I cant see the trace information. thanks in advance regards /prady -- htp://prady.livejournal.com
