Okay, I'm not all that knowledgeable about this one, but I'll give it
a shot. When I installed 3.4, I had a number of silo overflows when
using my modem. It never got up into the thousands. At most, it hit
maybe 200 during a typical web browsing session.
I was unable to determine exactly what that message meant, but thought
it must be that too much data is going through some part of the kernel
too quickly for it to handle. Knowing that my system is easily able
to keep up with my modem, I figured it must be a configuration problem
somewhere (duh).
I started with the BIOS, ensuring that my onboard controllers were set
up correctly. While I was at it, I checked everything else out as
well, discovering that I had a couple of other settings a little bit
off from what I actually wanted.
Next, I went through the kernel configuration and triple checked every
line that dealt with any of the ports, making extra sure that they
matched the BIOS settings and that they were how I wanted them. I
also made sure the kernel ppp stuff was configured correctly, since I
only used the modem with ppp anyway.
Then I recompiled my kernel, did a cold boot, and the problem was
gone. I don't know which stage fixed the problem, since (stupidly) I
was debugging a lot of other things at the same time in an impatient
rush to get the system "perfect". Somewhere in there, 90% of my
problems went away, though.
This doesn't give you much information, and I'm sorry about that.
It's just a pointer for places for you to look. It's obvious that
you're starting to get frustrated, understandably. Try to keep your
head about you. The problem you're having can be fixed - it's just a
matter of finding out how. Most of the people here are more than
willing to help, but most will stop helping if they feel they are
being yelled at for not contributing their *voluntary* time for a
specific problem.
Check your BIOS, then your kernel, then your ppp settings,
THOROUGHLY. Write again and if it doesn't fix it and I will try to
find some more information for you.
