I just upgraded my Kernel version from 2.6.17 to 2.6.18. Although I didn't installed the default kernel from debian repo (2.6.18-4-686). I re-compiled the kernel taking the existing .config file from 2.6.17 and then made few changes. I compiled the kernel debian way.
Now, during the boot with this new kernel I get these messages 7-8 times right in the beginning of the boot process:
modprobe: FATAL : could not load /lib/modules/2.6.18-gc1/modules.dep NO such file or directory
After that, the system boots fine and everything works normally.
Also, during this upgrade from 2.6.17 to 2.6.18 I also upgrade my debian system from Debian Sarge to Debian Etch.
I did some research and someone said that it is a bug in the make-kpkg package? I am not sure what to do next? Can I get rid of those messages or those messages are just normal and I should not worry about them.
