Sorry, but I missed this point as I got involved a little late and for that I apologize. This freeze makes sense in light of the 2.4.20/ext3 issue beign known, and switchign to reiserfs would make sense too. > this will hopefully fix my xrun difficulties. but what you said makes > sense, so i changed the fs of my root partition from ext3 to ext2 in the > /etc/fstab and rebooted. guess what? it still mounted as ext3! why is > that?!? I do not know. It is my understand and my experience that if I change fstab to say ext2 and reboot, as you did, then df -T will say ext2 and not ext3. Strange. > just to make sure, i issued a "jackstart --realtime -d alsa -d > hw", and guess what else? the system froze, just like it should. Yep, if you are mounted ext3, then the freeze is expected. > > is there another way to mount my root partition as ext2? ...last chance > before everything gets converted! :-) Not that I know of. > and... how would one change the journalling commit time, anyway? Not sure. I'm looking at man pages but not spotting how to do it. I have a vague memory of running across this before, but I don't know where. There are some kernel patches out there dating back to last year, along with some technical info, but possibly those require a kernel recompile which is a pretty drastic step for you to take right now. http://lwn.net/Articles/5584/ Here's one interesting thread I found with some interesting info: https://listman.redhat.com/pipermail/ext3-users/2001-November/002152.html I'll continue to poke around for what I saw. It was when I was first researching reiserfs. > another > thing you mention in the 'xruns vs disk activity thread' is turning off > chrond... can you elaborate on that as well, pls? ps -aux and kill the crond process as a test. ntsysv on Redhat, turn off crond and/or anacron as a test. I don't recommend running all the time with cron turned off, but it's certainly OK to turn it off and see if it effects your low level xruns.
