Subject: [Qemu-devel] weird qdev error
Date: Sun, 12 Feb 2012 19:07:44 +0200 [thread overview]
Message-ID: <20120212170743.GA3375@redhat.com> (raw)
I got this assert when working on qemu: pci hotplug
callback failed so qdev_free was called.
(gdb) where
#0 0x00007ffff5fa1905 in raise () from /lib64/libc.so.6
#1 0x00007ffff5fa30e5 in abort () from /lib64/libc.so.6

(gdb) frame 6
#6 qdev_init (dev=0x7ffff9124e60) at /home/mst/scm/qemu/hw/qdev.c:149
149 qdev_free(dev);
The problems seems to be that
pci_qdev_init calls do_pci_unregister_device on
hotplug error which will free the device twice?
