With the latest RTEMS, System > Shutdown > Reboot hangs in
yaffs_guts.c:yaffs_flush_file_cache
A bit of investigation reveals that dev->cache is NULL. The call
stack at this point in time looks like this:
rtems_yaffs.c:ycb_fsunmount
rtems_yaffs.c:rtems_yaffs_os_unmount
yaffs.c:unmount_handler
yaffs_guts.c:yaffs_flush_whole_cache
yaffs_guts.c:yaffs_flush_file_cache
The function that sets dev->cache to NULL is
yaffs_guts.c:yaffs_deinitialise
It is called by rtems_yaffs.c:ycb_fsunmount _before_
rtems_yaffs_os_unmount.
I'm not sure how to solve this. Perhaps yaffs.c:unmount_handler (in
flickernoise) should simply not call yaffs_flush_whole_cache and
yaffs_deinitialise ?
