(Responding to my own post) I've partly figured out the problem. It is caused by trying to boot a different kernel from the one under which s2disk or hibernate (not sure which) was invoked. Before I ran across the obscure warning against trying this, I had purged the offending kernel. Worse, the problem is passed along to new initrd.img files every time update-initramfs is called. So I ended up with three borked kernels, none of which booted. Luckily, I was able to mv initrd.img-(uname -r).bak into place, else my machine would have been bricked. So my questions are: 1) How does one get rid of an old s2disk/hibernate setting that demands to run "PM: Starting manual resume from disk"? 2) Can update-initramfs be instructed to ignore that old setting? 3) Ideally, can this problem be addressed from within the busybox: (initramfs) into which one is dumped when trying to do it the wrong way/ Until one of these questions is answered, it seems to be impossible to install any new kernel. SO BE WARNED: If you save to disk or hibernate, DON'T try to resume from a different kernel. BTW: Mightn't there be a more prominent warning against this mistake? -- johnrchamp...@columbus.rr.com ==================================================== GPG key 1024D/99421A63 2005-01-05 EE51 79E9 F244 D734 A012 1CEC 7813 9FE9 9942 1A63 gpg --keyserver subkeys.pgp.net --recv-keys 99421A63
