Re: PROBLEM: IO lockup on reiserfs FS.

[David Niklas]

I should add that in chasing down this bug I have tried all the IO
schedulers available (noop deadline and cfq). Cfq is the one I'm now
using to reproduce this.

Also, I don't know if it makes a difference, but when the system first
starts up it takes 20m to get from the login manager to having my web
browsers restart and get all their pages from online. It might be because
there is a lot of IO going on or it might be that there are several
stalls in the scheduling; just not bad enough to cause a hung task
problem like above.
