Revision d46f7c4df342c27cea676939d7c005f1e86173e9 authored by Dmitry Kravkov on 17 April 2013, 22:49:05 UTC, committed by David S. Miller on 18 April 2013, 19:03:25 UTC
When loading after UNDI (e.g., Boot from SAN) the UNDI does not gracefully yield its resources; The bnx2x driver handles that release itself. During the manipulation required to release those resources, it's possible for the UNDI to try and write to memory regions which are no longer accessible, causing the PCI bus to prevent further writes from the chip. This would in turn cause DMAE timeouts later on in the driver, as the driver will be unable to use the chip's DMA engines. This patch prevents the chip from actually writing through the PCI bus in said scenario, thus allowing the release without the unfortunate by-product.
