Hi folks! After seeing the Oops below (and rebooting), I looked into /proc/ksyms (because ksymoops complained about mismatches), and I could not find system_call, do_page_fault, etc. Shouldn't they be there? When doing ksymoops with /proc/ksyms I found recursive calling of do_brk, which for sure is not the right thing. The machine is a dual PII-450, kernel is 2.4.4 vanilla with Neil Brown's knfsd-patch. ---------------------------------------------- ksymoops 2.4.0 on i686 2.4.4.
