 The patch appears to work. The process no longer hangs when the SD card =
 is removed while it is mounted. The patched kernel did hang on startup =
 the first time I booted it up but I didn't manage to reproduce that on =
 the next few boots. The last thing it printed was "Starting xdm." The =
 fan was going so it may have been dumping core, but I didn't consider =
 that and forcibly rebooted after a minute or two had passed, but perhaps =
 that was not enough time. I would guess that this boot hang is unrelated =
 to the SD card issue.
 
 Thanks!=
