Box wont boot after kernel upgrade "Dump Card State Ends" error with scsi card

Box wont boot after kernel upgrade
I get the error....
Dump Card State Ends
....
Giberish
.....
Yikes! There is a loop in the free list!

That error keeps repeating.

This happened I recompiled the kernel with no module support. The same kernel boots ok with module support.

How can i get rid of that error with my "no module" kernel?

"How can i get rid of that error with my "no module" kernel?"

Scsi harddrives need modules to be loaded in an initial ramdisk before booting. You make this with mkinitrd which lifts modules to load as specified in /etc/modules.conf You then need to modify your grub or lilo config to use this ramdisk. Have a look at man mkinitrd.

How can I get it to boot off the scsi drive and then still not allow other modules not to be loaded on the fly, for security reasons?

I dont want a hacker with root access to be able to load a module to the kernel on the fly, how can I do that?

I think your slightly missing the security point here. If you have a hacker with root access on your box, him loading kernel modules are going to be the least of your worries. What can a hacker do with a kernel module that he cant do with a userspace program?

Also, if he has root access, he could compile another kernel which does load modules, set it as your default kernel and reboot.
