Bug#427905: Regression from 2.4 to 2.6: Unusable serial internet connection
Package: linux-2.6
Severity: normal
Tags: etch, sid
Hi guys,
I have a K6-II computer using an analog modem connected to the legacy serial port.
I am experiencing the following regression with the kernel 2.6 series:
After having dialed into the host,
* either the negotiation does not really work (no response from the other side in my log files) and pppd terminated
* or the connection is set up and after a short while stops to function yet pppd does not terminate by itself: For example the first web page is displayed correctly (not from cache!) and then the second or third fails.
I tried several debian kernels (486er variant): some 2.6.16 version, the 2.6.18 from etch and the current 2.6.21 from unstable. The behaviour is always the same - maybe even worse in the 2.6.16 version.
I also tried an analog modem connected to the USB port. The problem is there as well.
A have never had problems with the 2.4 kernel series - booting into etch with the 2.4 kernel (k6 variant) from sarge solves the problem. Dial in works and connection remains stable.
Any suggestions how to track down the problem?
Best regards,
Ralf
