I had to replace a disk (the one with all of the home directories on
it) on an FC3 box, and so I bought a new drive (particulars
unimportant).
To make a long story short, I decided to put FC4 on this box, and so I
installed the new drive and put the root filesystem on it. I still
have the old FC3 root drive and can boot to either for comparison...
Under FC3, I have no network problems that I can detect; however, under
FC4 there are two distinct (related? no idea) problems which have
eluded me. I have tried looking up both of these in the archives, but
have had no luck (some similar issues, but nothing exactly like either
of these unless I missed them).
Problem 1: network card goes to sleep.
This machine has 2 network cards, both on-board. The 1GB card L(Intel
82540EM) goes to the smartswitch to tolk to the local network, and does
not show any problems.
The other card (nVidia nForce2) is a 100MB card and talks to the DSL
modem. Periodically I cannot connect to the internet at all - or even
ping the DSL modem. This happens irregularly but about 5-10 times/day.
If I reboot back to FC3, the problem does not occur. Network
configurations between the two (FC3/FC4) are as identical as I can make
them. The first few times the problem occurs, sometimes retarting
networking works, but eventually a full sys reboot is the only thing
which works.
Problem 2: slow local network.
Under FC3 throughput on the LOCAL network (1GB lan) is very fast.
Under FC4, the best I have seen is ONE transfer of about 1.2 MB/s - and
throughput drops to as low as 50-75KB/s at times. Again, this does not
occur under FC3 but does under FC4. Again the same setup as nearly as
I can make it. No workaround found so far.
Any suggestions would be greatly appreciated.
