The patch mentioned in comment #3 had been included in the kernel here:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7734f6e6bcd7ba78b00e93e74a4ddafd9886cdea
So I guess we can close this bug nowadays? Or can you still reproduce this issue with the current kernel and current version of QEMU?

There hasn't been a reply to my question in the last comment within
months, so I assume nobody cares about this anymore. So I'm closing this
ticket now...
