Well, I thought the issue was with x86_64 but the same thing is happening on my 32 bit machine too.
[root@smitty2 qemu-0.11.0]# ./i386-softmmu/qemu -serialice /dev/ttyS0 -hda /dev/zero -L ../bios > /home/joe/serialice_dumps/ipmsnorg.txt Segmentation fault (core dumped)
And the log just stops after: SerialICE: Open connection to target hardware... SerialICE: Waiting for handshake with target... target alife! SerialICE: LUA init... SerialICE: Starting LUA script SerialICE: Registering physical memory areas for Cache-As-Ram: Registering physical memory at 0xffd80000 (0x00080000 bytes)
Any ideas???
