Hello.
	One month ago Till Straumann wrote about the bug in 
'new_exception_processing' code. Where there some actions about this since 
that time or the problem exists in MPC860 BSPs?
	Thanks ahead.

PPC BSPs other than mpc8260ads!!!

PR288 never made it to other PPC BSPs.

watch out

As a quick workaround, you can delete the line

_ISR_Flash()

in the file cpukit/score/src/watchdoginsert.c
(your IRQ latency will go up)

(old_exception_processing BSPs are not flawed)
