[Qemu-devel] qemu crash in aio_read

[Adam Jacob Muller]

Hello,
I am experiencing a crash in qemu when trying to load an existing  
known-working image:

This is attempting to boot with a basic copy of gentoo, any ideas what  
could cause this?

I can provide any additional debugging information or test patches etc.
