Modified files:
sys/alpha/alpha interrupt.c
Log:
insert a magical second memory barrier prior to calling draina() in
badaddr_read(). This fixes 'machine check in pal mode' halts on
ev5 2100As.
MFC candidate -- after spending 6 hours tracking this down, I checked and
discovered that it has been in NetBSD for over a year, so it should be safe
for MFC into 4.3-RELEASE
