Hello, after installing the latest kernel update for the ptrace security issue on a SuSE 8.0 system, the new kernels panics while booting with the message "VFS: unable to mount root fs". My possibilities to analyze this problem are very limited since the system in question is an important 24x7 production system to which I only have remote access and when the system fails to boot this can only be fixed with the help of a local engineer. This is why I'm asking this list if anyone has experienced this problem before and possibly even has a solution for it. As a note, the new kernel works fine on two SuSE 7.1 systems. Some information on the system: SuSE 8.0, SuSE SMP Kernel 2.4.18-64GB-SMP for 2 P-III CPUs, 1 GB RAM, 2 SCSI drives with Adaptec SCSI controller. Root-Filesystem is ext3 INITRD_MODULES="aic7xxx usbcore jbd ext3" Bootloader lilo mk_initrd und lilo after installation of the new kernel ran without any error messages. After re-installing the old SuSE 2.4.18 Kernel with the security leak the systems boots up fine again. Thanks in advance Stefan
