Right. The kernel I'm using has this. But if you look back a bit through
the list, you'll see I had problems on ar71xx still - on Buffalo G300NH.
There was some grief in the serial handling, and I had to go via u-boot
to completely reset things. I mention this in case anyone else is
trying kexec.
My device is ar71xx too. And actually I had some (another) issue as
well. I discovered that if network device(s) initialization is performed
before kexec, the new kernel starts successfully but later the system
ends up rebooting spontaneously.
I didn't mention this yet because I found this problem also "fixable" by
compiling network drivers as modules and delaying their loading until
after kexec might have been attempeted.
So currently, I do have it all working prefectly fine here.
