I'm curious - what exactly do people find they can run reliably with no hangs on a known good system? On ec2 instances I find even runltp -f syscalls to hang. I know, I know :) I do intend to look into it. But is there anything people find they can use as a gross "this works on good kernel, let's see if it breaks on test kernel" metric? -serge ------------------------------------------------------------------------------ BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA The must-attend event for mobile developers.

That is probably sched_yield() testcase, the culprit is writing to stderr while plaing the ping pong with sched_yield() which would make the disk writing thread lock (not really kernel bug as the test blocked all cpus but one which on which it plays ping pong with sched_yield()). At least it locks with some older kernels. I will commit a patch that just removes useless printf(). -- Cyril Hrubis chrubis@suse.cz ------------------------------------------------------------------------------ uberSVN's rich system and user administration capabilities and model configuration take the hassle out of deploying and managing Subversion and the tools developers use with it.

You can save a lot of time (hours) if you omit the aio testcases, these are submitting a lot of aio requests moving gigabytes of data back and forth. -- Cyril Hrubis chrubis@suse.cz ------------------------------------------------------------------------------ uberSVN's rich system and user administration capabilities and model configuration take the hassle out of deploying and managing Subversion and the tools developers use with it.
