2.0.12 (May 13th, 2004) - Flag driver threads with PF_FREEZE to support software suspend. 2.0.11 (May 7th, 2004) - Avoid split-completion bugs in certain PCI-X chipsets by breaking up large completion entry DMAs on ADB boundaries. 2.0.10 (April 9th, 2004) - Return "command timeout" status instead of "selection timeout status" to the SCSI mid-layer in response to selection timeouts. While the latter may seem more correct, the mid-layer will not offline devices suffering from persistent selection timeouts. This leads to extremely long recovery times for devices that go missing. Returning command timeout status causes the mid-layer to enter recovery and eventually offline persistently missing devices.
