I have just seen your latter problem. I am running Debian unstable (as
of late Feb) and building Kernel 2.4.24. I use debian's make-kpg, when
doing dpkg -i I get the above error. Because I had not yet installed the
matching modules package (for i2c) I get some unresolved symbols. The
lockup seems to occur during or just after the depmod. I'm still looking
into it...
