While trying to debug the init panic I reported earlier ("Panic: init dying
with 4.7 kernel"), I tried booting my system with the boot floppies and
using the fixit floppy. However, any time I ran any of the programs on the
fixit floppy, they segfaulted. Even if I mount up the 4.7 fixit on a 4.6
system, the same thing happens (I attempt to ktrace the execution below):
<root@cedar:/tmp> # echo foo | ktrace -id /mnt/stand/grep foo
zsh: done echo foo |
zsh: segmentation fault (core dumped) ktrace -id /mnt/stand/grep foo
<root@cedar:/tmp> # kdump | m
12546 ktrace RET ktrace 0
12546 ktrace CALL execve(0xbfbffba7,0xbfbffaa8,0xbfbffab4)
12546 ktrace NAMI "/mnt/stand/grep"
12546 grep RET execve 0
12546 grep PSIG SIGSEGV SIG_DFL
12546 grep NAMI "grep.core"
Unfortunately, the ktrace gives no info.
I'm stumped at this point.
