Most likely, the old kernel is still installed. rpm -qa|fgrep kernel should list the kernels installed. To boot an old kernel, stop grub at the booting stage and see if the old kernel is listed. > > 2) How have to do to trace the error program & find what is wrong... > > I run Fedora core 4 on a pentium 3 proc.

You could try strace and see what happens. boot old kernel: strace -o oldkernel.log yourprogram boot new kernel: strace -o newkernel.log yourprogram compare the two files newkernel.log and oldkernel.log Mogens -- Mogens Kjaer, Carlsberg A/S, Computer Department Gamle Carlsberg Vej 10, DK-2500 Valby, Denmark Phone: +45 33 27 53 25, Fax: +45 33 27 47 08 Email: mk@xxxxxx Homepage: http://www.crc.dk -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
