The sequence is as follows: rtnlnewlink()-> _devchangeflags()-> _devopen()-> devsetrxmode() - > # disables BH and grabs "dev->addrlistlock" idpfsetrxmode() -> # proceed only if VIRTCHNL2CAPMACFILTER is ON _devucsync() -> idpfaddmacfilter -> idpfadddelmacfilters -> idpfsendmbmsg() -> idpfmbclean() -> idpfctlqcleansq() # mutexlock(cqlock)

Fix by converting cq_lock to a spinlock. All operations under the new lock are safe except freeing the DMA memory, which may use vunmap(). Fix by requesting a contiguous physical memory for the DMA mapping.
