When I create an xfs filesystem and run
'stress' (http://weather.ou.edu/~apw/projects/stress/stress.html) I can
induce a system freeze (hang, no panic). There are no issues if I create
a jfs filesystem (on the same disk) or run 'stress' on a different disk
(ext3)
I'd like to know how I could go about debugging this, otherwise I will
have to switch filesystem types.
Details:
% stress -d 2 --hdd-noclean --hdd-bytes 3G --verbose
