Package: qemu
Version: 0.9.0+20070816-1
Severity: minor
I was running a raid system inside qemu and tried to simulate a disk
failure by eject -f hdd. The system continued to work. I then entered
sync at the shell prompt which made qemu segfault.
Is this really a bug? I mean I had to force qemu to do so.
Is it reproducible?
See my backtrace below.
