hi,
i've some trouble with the new kernel (2.2.5) from the SuSE-distribution
6.1. this problems didn't occur with the old distribution 5.3. i don't
understand something from the kernelprogramming but i've read the
oops-tracing.txt and now i send you the output from the ksymoops
program. i'm sorry, if this is not the right address for my problem, but
i don't know, which person to write. the exception occured only
sometimes within different processes (netscape, sort, mandb, ...) and it
is for me very mysterious... :-))

now, the ksymoops output:
