I just re-verified it on current stable

Can you try the patch I just posted?
Applied this one:
[Qemu-devel] [PATCH +stable] block: don't attempt to merge
overlapping requests
quick tests shows it works correctly so far.
At least it went further than before, not
stopping at the "usual" sector 3145727872.
Hmm. Ide has no queue, hence no mergeing,
that's why it does not occur with ide,
right? :)
Yes.
Interesting...
Yes. Why would Linux post overlapping requests? makes
0xffffffff00000000 sense.
There may be a guest bug in here too. Christoph?
