[Qemu-devel] Framebuffer corruption in QEMU or Linux's cirrus driver

[Andy Lutomirski]

Running:

./virtme-run --installed-kernel

from this virtme commit:

https://git.kernel.org/cgit/utils/kernel/virtme/virtme.git/commit/?id=2b409a086d15b7a878c7d5204b1f44a6564a341f

results in a bunch of missing lines of text once bootup finishes.
Pressing enter a few times gradually fixes it.

I don't know whether this is a qemu bug or a Linux bug.

I'm seeing this on Fedora's 3.13.7 kernel and on a fairly recent
3.14-rc kernel.  For the latter, cirrus is built-in (not a module),
I'm running:

virtme-run --kimg arch/x86/boot/bzImage

and I see more profound corruption.
