** Changed in: qemu Status: New => Fix Released -- qemu i386-softmmu segfaults on i386 while testing kdbg hardware interrupts https://bugs.launchpad.net/bugs/501177 You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. Status in QEMU: Fix Released Bug description: I tried to boot a kernel with enabled kgdb and kgdb self checks with qemu emulating i386. It works with amd64, but crashes with i386. Tests were done with 19e65b47f60c68d7e8c96aa0a36223c5a0d3422b and qemu 0.11.1-1 on Debian sid.
