I got this output from ksymoops on a 2.4.19-aa1 kernel. Does anyone know
if this stack looks corrupt? Looking at each compared to each other, I
believe so, but I just wanted some confirmation of this. Your urgent
help is most appreciated.
The recent output is taken from a production box that won't stay up for
more than 7 days at a time. The older output, is from an identical box,
running the same kernel, under different circumstances.
TIA.
