Description Rasmus Melgaard 2004-11-09 07:19:16 UTC
One or more of the gentoo-patches to the kernel tree 2.6 causes some sort of stall in the TCP-traffic, no browser (not even links2 in console-login-mode) can get the homepage of But if you which to vanilla-sources (2.6) then it works. Tested on almost all versions 2.6.7 and 2.6.8 of gentoo-dev-sources, switched to vanilla 2.6.8 and it worked in all browsers (links2, firefox, mozilla, konqueor). 
 - During a TCP-stall, Ethereal shows an ACK being sent to the web-server, but nothing happens after that, maybee the 'ACK' is not sent after all?
Comment: I have see this behaviour on several web-servers and I think they might all be MS-IIS, but not all MS-IIS produce the failure!

Reproducible: Always
Steps to Reproduce:
1.change kernel of Gentoo 2004.2 to gentoo-dev-sources version 2.6.8-r10 ( emerge =sys-kernel/gentoo-dev-sources-2.6.8-r10)
2. Build the kernel, i'll try to attach my kernel.config
3. links2 and see it stall (around 5.5 k into the page)

Actual Results:  
Stall web is not loaded

Expected Results:  
Load the page

Did a simple test with 2.6.9-gentoo-r4 kernel in non-graphical mode, used links2, command: "links2" 

and the page loaded , didn't seem like there was any problems, thanks!
