i've been trying to figure out what in the world the following message means or what generated it but to no avail. no amount of googling or digging has revealed anything and this is the last step before i call apple. to give a bit of background here, i recently migrated using the assistant from a black 2008 macbook to my new aluminum macbook pro 13 and that in itself went smoothly but since then, my macbook hangs without even the SBB and just a frozen cursor for 10 to 20 seconds and on checking the console i find multiple (20 or so?) successive instances of the following: 23/Jul/09 23-Jul-09 14:42 kernel /drv/ MacAsyncDevice.cpp:229 Wait for host_wait_work_complete_async_device (02:00) finished with timeout. can anyone out there figure out what could be causing this? i've gone through the general troubleshooting steps including creating another account and have pretty much concluded its a software error. UPDATE: here's another error that i feel may be related to the one above and has been also happening - although less frequently - since i migrated to the new machine: "23/Jul/09 23-Jul-09 16:26 /usr/libexec/hidd IOHIDEventQueueEnqueue: Error enqueuing memory. (0xe00002e8) "
