Hi, I have very strange problem , I have installed ethereal through #yum -y ethereal ethereal-gnome every thing went well. then I load ip_conntrack_pptp module using # modprobe ip_conntrack_pptp; it took a lot of time and seem not responding to any kind of terminates (ctrl-c).the cpu usage was 100% for a long time. after rebooting when udev started on next reboot it give me continuities messages of udevd-event[117451] run_program: exec of program '/sbin/modprebe' failed when I press Ctrl-c the boot up process continue to normally until network start it gave ipv6_test not supported by kernel. I did not change anything that relevant to the kernel. I am running kernel 2.6.18-1.2846 i686 smp; when I boot with the older kernel the same problem occurred . I have backup of my /etc, resoring the backup didn't help. is there anyway to solve this problem.
