Weird. And of course you are using speed 115200, or at least 57600, in your ppp configuration, right? (just ruling out common misconfigurations). Check also for IRQ conflicts between your modem and your NIC. Maybe they're being forced to share an interrupt, and one or both do not like that. > Booting the 2.2.20 Debian kernel from the Woody installation results in > normal transfer rates, however I must change /etc/default/pcmcia back to > i82365 as the rate with yenta_socket is poor. > > Thus I'm inclined to think that for some reason the yenta_socket code is > to blame, but I'm tired of fighting it.

IMO you'll miss 2.4 if you go back to 2.2, and you'll miss woody even more, if you go back to potato. There should be no need for that. yenta is needed only for the *kernel* PCMCIA support. I don't use that myself, I use a custom 2.4.18 kernel with modules from pcmcia_cs (that is, I use i82365, not yenta_socket). What I do is get the kernel-source, pcmcia-source, and kernel-package packages. Uncompress the PCMCIA tarball, so you end up with a "modules" directory right under "/usr/src". Configure the kernel with no PCMCIA support (that's right, disable it completely). Run the usual make-kpkg kernel_image and, after that, a make-kpkg modules. You should probably make the rest of the PCMCIA packages, as well, to avoid version problems with the kernel. See the make-kpkg and pcmcia-source docs for details. That should give you a pcmcia modules package, with modules from pcmcia_cs, not from the kernel. Then you'll configure for i82365 again and, if your problem is yenta, it should be gone. Hope this helps. -CR
