Could anyone provide QE the steps to reproduce this bug ?

Comment 3 Dmitry Fleytman 2013-05-02 08:43:28 UTC

Hello Mike,

Basically what you need is to make VM hibernate and re-run the qemu.
However this bug is a race condition by nature so it does not show up on every hibernation cycle, we saw it almost every time on MPE test while working on BZ#920928.

Another incarnation if this bug is device queues stuck after NDIS reset callback invocation. This explains failures of other HCK tests like MPE, RESET and MINI6SEND.
