[Qemu-devel] [Bug 1769189] Re: Issue with qemu 2.12.0 + SATA

[Andrew Randrianasulu]

I think I was hit with very same bug.

I did bisect with 2.11.0 as good point and 2.12.0 as bad point.

configure was 

setarch 
i486 ./configure --prefix=/usr --disable-gtk --enable-virglrenderer 
--enable-sdl --with-sdlabi=2.0 --audio-drv-list=alsa,oss 
--host-cc=/opt/gcc49/bin/gcc --enable-opengl 
--extra-cflags="-I/usr/X11R7/include -O3 -march=i686 -mtune=native -m32 
-Wno-maybe-uninitialized -Wno-nested-externs 
-Wno-implicit-function-declaration" --disable-werror 
--target-list="x86_64-softmmu"

and launch command

x86_64-softmmu/qemu-system-x86_64 -cdrom 
~/Downloads/ISO/slax-English-US-7.0.8-x86_64.iso -enable-kvm -m 1G -M q35

    replay: avoid recursive call of checkpoints

    This patch adds a flag which denies recursive call of replay_checkpoint
    function. Checkpoints may be accompanied by the hardware events. When event
    is processed, virtual device may invoke timer modification functions that
    also invoke the checkpoint function. This leads to infinite loop.
