Hello, Reporting this on behalf of ric. He was running the following fs_mark command ./fs_mark -d /mnt/test -s 20480 -D 64 -t 8 -F Seems it hung and wasn't making any progress. He managed to get some sysrq-t, which is at http://people.redhat.com/jwhiter/fs-mark-hang.txt towards the bottom of the document. He could ctrl+c and unmount the fs so its not a hard hang. Looks like we've just locked up behind a page lock somewhere. I have to run off to class so I can't look into it too deeply so throwing this out there hoping somebody else figures it out :).
