I can scarcely believe what I am about to put down, here, but this is
exactly what happened on my SuSE Personal Edition box.

I installed 9.1 & hooked up my 3Com ISDN modem, which worked pretty well
except for the fact that it would only work on one channel. I used it
anyhow, for a few hours w/o problems. I decided to check the updates &
installed each, not selecting to remove the files when done.

Roughly 18 hours later, the modem was online & I was doing my thing when
suddenly there was absolutely no throughput. I was online, yes, the modem
light indicating such was lighted. E-mail would not fetch, browser would
not fetch.

I had a backup ISDN modem & hooked that one up & dialed. It hooked up on
both lines, and worked non-stop for roughly 18 hours, then quit ...while I
was online, like before. I was listening to a RealPlayer feed it &
suddenly stopped. E-mail & browser would not fetch, as before.

Since this modem has reset capability I did the factory reset and tried
dialing, again. The box wouldn't even talk to the modem ...or if it was,
there was no indication.

I moved the modem to my XP box & was online in roughly 3.5 seconds, as
always. I sent a couple e-mails and then moved the modem back to the SuSE
box for one last-ditch effort before pulling the plug on the installation
...and it worked.

As I indicated to a couple people privately, I am really damned frustrated
and a bit hot about it because I cannot seem to get to the bottom of the
problem. SuSE 9 Pro stopped working with the same modems immediately after
updates were applied ...unless and until SuSE 9 was reinstalled from
scratch and NO updates applied EVER. SuSE 9.1, on the other hand,
selectively works or doesn't work ONLY after the updates were applied!

ANY help will be gratefully received ...whether the solutionworks, or not. I don't even know where to begin!!

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 problem.

Thanks for confirming what I have exprienced (very, very close to being
the same as you). See my message I sent yesterday with the Subject of SUSE 5.1 - BAH!


I am not young enough to know everything.
