Re: [SeaBIOS] [Qemu-devel] [PATCH 0/3] switch to seavgabios

Negative also here:
Don't see anything on screen on startup...

From log, latest qemu-kvm git version:
Running option rom at c180:3d4e
Running option rom at c180:3da2
Running option rom at c180:3df6
Running option rom at c580:0003
qemu-system-x86_64: /root/download/qemu/git/qemu-kvm/exec.c:2641: 
register_subpage: Assertion `existing.mr->subpage || existing.mr == 
&io_mem_unassigned' failed.

Startup is done with the following command:
/root/download/qemu/git/qemu-kvm/x86_64-softmmu/qemu-system-x86_64
-drive file=1.img,media=disk,if=scsi,bus=0,unit=0
-drive file=2.img,media=disk,if=scsi,bus=0,unit=1
-drive file=3.img,media=disk,if=scsi,bus=0,unit=2
-boot order=cad,menu=on
-m 2048 -k de
-vga vmware -vnc :0
-bios /root/download/seabios/git/seabios/out/bios.bin -chardev 
stdio,id=seabios -device isa-debugcon,iobase=0x402,chardev=seabios
-option-rom BIOS/V4.19/8xx_64.rom
-device rtl8139,mac=00:02:44:92:87:6a,vlan=0,romfile= -net 
tap,ifname=tap0,script=no,downscript=no,vlan=0

Backtrace isn't valid.

Old integrated BIOS is valid and works well.

Ciao,

Can you build with ./configure --disable-pie --enable-debug and retry?
