After making extensive enquiries elsewhere I have been advised to post this question to the kernel mailing list. Joseph Anthony wrote recently to the list about a similar matter (I think). The problem: symptoms It concerns the behaviour of Netscape after upgrading from kernel 2.2.16 to 2.4.0. With the new kernel Netscape locates and connects to a URL, and sometimes begins to download, but then it just sits there indefinitely (without downloading any data). This happens quite consistently since I upgraded to 2.4.0 (about 2 weeks ago). ppp, telnet, ftp all function satisfactorily as far as I can determine (however that's not to say that the problem doesn't originate with ppp in the kernel). There are a few packet errors (about 1 per 1000). Netscape continues to function well with Linux kernel 2.2.16 -- but not with 2.4.0. People have suggested various things (eg upgrading programs to later versions). I have tried most of them, without success. Somebody recommended I turn to the kernel mailing list. If this is not the right place for my enquiry I apologize (where else?). But if somebody recognizes these symptoms I would be very grateful for a diagnosis...
