2.2.7 oops trying to call right after it frees unused mem. -ac1 will let me get
to /bin/sh (using lilo's init= feature), but causes an oops if I do something
as simple as an ls -l (this is really wierd: just plain 'ls' doesn't do
anything).
Also, I am using egcs 1.1.2 (2.91.66) as the compiler.
here is the output from ksymoops on 2.2.7-ac1.
