I used kexec to reboot a new kernel, but I found that , the second
kernel stopped when calling 'prom_getenv("memsize") ' in booting.
That is , kernel: setup_arch-->prom_init-->'prom_getenv("memsize")' failed
So I checked the code in kexec-tool , and I found that ,in
mips-simple-setup.S, register a2 was set to 0, which was passed to
the second kernel as envirment variable address.
I guess here a2 should not be set to 0 , is it a BUG in kexec-tool ,
when dealing with mips?
ps: I don't have mail address of the authors who wrote mips support
for kexec , Francesco Chiechi, Alessandro Rubini , Tvblob s.r.l.
So I wrote directly to this maillist to search for help.
More information about the kexec
