Hi,

I'm seeing quite frequent corruptions of the VESA frame buffer with
Linux guests (vga=0x317) that are starting with KVM kernel modules of
upcoming 2.6.36 (I'm currently running -rc7). Effects disappears when
downgrading to kvm-kmod-2.6.35.6. Will see if I can bisect later, but
maybe someone already has an idea or wants to reproduce (just run
something like "find /" on one text console and witch to another one -
text fragments will remain on the screen on every few switches).

Jan
