Comment (by rtemsdev):

 There is no patch yet. We produce devices that are running very stable
 now, with the modification as noted in the issue description (commenting
 out the two lines in cpu_asm.S). But I have not been able to correctly
 identify all possible side effects nor run all tests (due to other
 problems).

 Updates for the links:

 Also see discussion here ("ticker hangs on bf537Stamp"):
 http://lists.rtems.org/pipermail/users/2013-October/027186.html

 Another occurence with similar outcome, maybe for the same reason ("bfin
 simulator problems"):
 http://lists.rtems.org/pipermail/users/2013-May/026692.html

 Probably in RTEMS since 2008, with background e.g. discussed here
 ("Problems with the blackfin port"):
