[Bug 131094] Re: Heavy Disk I/O harms desktop responsiveness

[Trey Blancher]

OK, it looks like the problem is fixed for me in both the stock 2.6.35
and +iofix provided by Brian Rogers.  There's still [kdmflush] and a
bunch of other programs causing a lot of I/O wait (according to top and
iotop), but the system is MUCH more responsive.  Usually when the
problem occurred, the HDD light would go solid for several moments
before I could use my system again.  Now, the pause is brief, much less
than two seconds if it ceases being responsive at all.  I mentioned
earlier that the problem still occurred shortly after boot, but that was
the HDD light I was referring to, not the perceived responsiveness of
the system.  So for me, the solution is to upgrade to 2.6.35.
