hey Christoph
I've tried this patch with ac9 and it doesn't seem to solve the problems I've
been having. Basically I can cause any system running 2.4.0-test1+ to lock
up without any messages to the console or log files. Right before the lockup
one can still login, but ps halts at the process that's about to cause the
lock up and top will not even run. If one tries to nicely shutdown the
machine locks. The process in question is multithreaded and basically mmaps
files read/shared and read/write/shared.
Okay I just finished another test. This one takes a while to kill the box.
Basically this program opens a 10GB file and has 100 threads reading and
writing to it. A mutex is used every time the file is accessed. Any help
would be appreciated. :)
