Hey, i had this issue on a Celeron something (the one prior to the |
26 |
coppermine series). |
27 |
|
28 |
After reading a bug on the FreeBSD site ( |
29 |
http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/34756 ) i worked out i |
30 |
could connect to anything with an ip matching |
31 |
[1-209].[1-209].[1-209].[1-209] (ie. if any section of an ip was >=210, |
32 |
it would time out) - i tried compiling with '-O0' however the kernel |
33 |
still didnt work, even after doing 2x 'emerge -e system' (after much |
34 |
pain getting all the packages onto the box) -- any help getting gfbsd |
35 |
working would be great! |
