Regarding CK speed improvements: I certainly did not do any controlled testing/benchmarking of how my system performs under the two kernels (vanilla and ck2), but I did notice applications starting noticably faster. If the difference had been negligible I would not say it was faster, but in my case it WAS noticably faster. For instance, an application that normally takes 2 seconds to start was about half that (somewhere in that range). Now I know we're talking miniscule differences here but if package compile time is affected as greatly then I stand to gain minutes, in some cases. When it's all compounded it could add up to something much more substantial. But, again, I did not to any kind of official benchmarking (but it would be fun to do and see the difference - I just wouldn't know how to procede).
Regarding wireless problems: I have a linksys wpc54gs v1 (broadcom 4306 chipset) wireless PCMCIA card. The first problem was the modules were not loaded but I got them loaded (modprobe bcm43xx). I had already configured my wpa_supplicant.conf file and have it set to start at boot in the background/waiting (-Bw), so that was ready. I had already configured wifi-radar with my wireless information. I attempted to connect via wifi-radar and it showed a connection but I could not ping the network. I downed/upped eth1 a couple times; I disconnected/connected wifi-radar a couple times; I tried pinging everything I could think of and nothing worked. I booted back to vanilla and tried the same with the same results, at which point I remembered that I have to 'down' my eth0 card otherwise my system attempts to use that nic to make it's connection, and since it's not wired into anything it fails. I'm sure if I would have booted back to the ck2 kernel and downed eth0 I would have had the same success; I just never got around to it. I'll probably give it a shot tonight and will let you know the outcome.
Question: In vl58, if my wired nic was not connected to anything it would not be 'up' after boot but it vl59 it is; is that normal? and is it possible to make it act like it did in vl58?
