Founds this a few lines lower: aio=2.4 This is used to force UML to use 2.4-style AIO even when 2.6 AIO is available. 2.4 AIO is a single thread that handles one request at a time, synchronously. 2.6 AIO is a thread which uses the 2.6 AIO interface to handle an arbitrary number of pending requests. 2.6 AIO is not available in tt mode, on 2.4 hosts, or when UML is built with /usr/include/linux/aio_abi.h not available. Many distributions don't include aio_abi.h, so you will need to copy it from a kernel tree to your /usr/include/linux in order to build an AIO-capable UML Apologies for spamming the list for nothing, I will go and find a hole to hide in now.
