I guess a single pci_read_config_word() would suffice. Though it would obviously be much better to identify the place in the driver which needs to have the write buffers flushed, and add a read() just there. The interrupt handler maybe (e.g. just before the return IRQ_HANDLED)? OTOH this may be some sort of timing problem, I mean the faster code may put too much stress on the SOLO chip. Doesn't happen here so I can't test the cure. -- Krzysztof Halasa Industrial Research Institute for Automation and Measurements PIAP Al. Jerozolimskie 202, 02-486 Warsaw, Poland
