Hi,
F19 kernel-3.9.8-300.fc19.x86_64 qemu-kvm-1.4.2-4.fc19.x86_64
If I start a complete F19 install in the guest and send the qemu process a SEGV signal, the host kernel starts giving me random kmalloc errors soon after, if I send a normal kill signal things seem fine.
CPU is Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz, on a HP 220z workstation.
I initially blamed bad RAM but this reproduces everytime, and I swapped DIMMs around
I haven't tested with upstream kernel/qemu yet, but I wondered if anyone else has seen this.
I noticed this because some work I was doing was segfaulting my qemu and then my machine would die a few mins later.
Dave.
