Bottom posting which is a pain in the arse..... but the posting police will
get you if you don't watch out....

I have been having a similar problem but may have found the problem.

I am running 9.0 but I *was* running with kernel 2.6.6. I also was having
thruput problems on a normal 56k dialup modem. Things wouldn't stop
completely, but the throughput was almost non-existant... really poor.

I was yelling at my ISP (and fortunately I have a good relationship with them)
and they were testing dialup response and not finding any problems... and
also said that I was the only one complaining. (and I believe them).

I tried different phone numbers, and a different (but the same type) modem
(USR V-everything) but nothing really changed. At one point I dialed into
another ISP and things got really good for awhile, but then slowed down
again. (sound familiar?)

At that point, I switched back to a 2.4.25 kernel and things have been a lot
different since. Pretty good thruput. So I am thinking there are problems
in the 2.6.6 kernel somewhere. NOTE: Both of these kernels are stock,
vanilla kernels from so SuSE has nothing to do with them.

Not sure how to shoot this kind of problem but I think there definitely is a
