You have to use the UPX beta version to be able to compress a linux kernel image.

Try to boot first without compressing your kernel with UPX. Since you have space on your HDD just copy your bzImage file and rename it linux. If that does not fix your pb then try without applying the grsecurity patch to your kernel. It could be that 2.4.21 grsec patch has the same flaw as the one existing in earlier version of 2.4.20 Let us know the results > What I did wrong? What I should do to boot new kernel version?

You can use non compressed version of the kernel if you wish. Jacques
