Hello,
I followed the instructions for updating to SL 5.3 (from SL 5.1 + latest yum
updates) on scientificlinux.org. It did not give any errors during the update,
but I think something went very wrong because now I have a rather long list of
problems such as:
1) During every boot, I get this message:
Bringing up interface wmaster0
Determining IP information for wmaster0... SIOCSIFFLAGS Operation not supported
SIOCSIFFLAGS: Operation not supported
The machine is frozen for about 2 minutes while it thinks about these
SIOCSIFFLAGS after which it resumes booting.
2) The option to connect to wireless networks through Network Manager is grayed
out. I have an Intel 4965AGN wireless card which worked perfectly fine before I
tried updating, but now it doesn't seem to see the networks anymore -- the
settings include a list of all of the connections with correct names and
passwords, but the system acts as if there is no network in range.
I think these two issues are related to the updated driver for iwl4965
in 5.3. SL5.2 used the iwl4965 driver whereas 5.3 uses the new iwlagn
driver. They use *different* firmware, so a user updating from 5.2 ->
5.3 with previously working wireless will experience the issues you
describe if the correct firmware is not installed.
In /etc/firmware you will need iwlwifi-4965-2.ucode (note the -2
revision is required by the new iwlagn driver).
RPMforge has the correct firmware packages (yum install
iwl4965-firmware). I'm not sure what SL firmware packages are available
nor what firmwares these packages contain.
The firmware is in iwlwifi-4965-ucode which is part of SLF 5.3 .

Hope that helps,
