Regression in virtio_net causing kernel BUG when running under VirtualBox (bisected)

["Thomas Müller" <thomas@mathtm.de>]

[-- Attachment #1: Type: text/plain, Size: 3373 bytes --]

Hello,

I'm running Linux under VirtualBox 3.1.6 with a single virtual CPU
without any third party drivers.

Commit 9ab86bbcf8be755256f0a5e994e0b38af6b4d399
(virtio_net: Defer skb allocation in receive path)
caused a regression which results in a kernel bug and subsequent
hang at every boot.

I have attached the complete output during boot.

Please CC me on reply as I'm not subscribed to the mailing lists.


Best regards,
Thomas
