Hi David
I have not tried yet to repro #49361 on 3.6.6, but, as you say, if
there are no core VM changes, I am confident I can do so just by doing
# echo always > /sys/kernel/mm/transparent_hugepage/enabled
I am at your disposal to test further, and, if there are patches, to
try them out.
Note that I only once experienced a crash for which I could not find
relevant info in logs. But the hanging processes issue could always be
reproduced consistently.
have a nice day
