Yeah, I still can't get reproduce that reliably - I remember seeing it
at some point but then dismissing it for another, higher-prio thing. And
now the whole memory is hazy at best.

But, you're giving me a great idea right now - I have this kernel
disassembler tool which dumps alternative sections already and I could
teach it to look for pathological cases around the patching sites and
scream.

Something for my TODO list when I get a quiet moment.

Thanks!
