Sadly no. I've done complete clean-up, backup and reinstall (QQ>RR) yesterday. Now I have:

3.7-rc6 is available now:
Code:http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc6-raring/
Works!
But, I'd be willing to swear, "network-manager" is getting flakier with each new rc :confused:Code:vindsl@Zuul:~$ uname -sr
Linux 3.7.0-030700rc6-generic
For instance, when I click on the NM indicator (in the top panel) there is a box for enabling networking, and not much else. Mind you, "networking" is enabled, but it runs like grunt.
If I check "Enable networking" it sends me a notification that I just disconnected. Then, when I check "Enable networking" a second time. NM connects, and works fine for the rest of the session.
Possibly, this is unrelated to the kernel, but I didn't notice it until the 3.7-rcs appeared... and I *think* it's getting worse. I could ignore it before. But, now, if I don't check the "Enable networking" box a couple of times, speeds are horrendous, my browser is slow and/or unresponsive, with 404s and so forth. Sometimes, I can't even log into machines on my LAN, in the next room, unless I go though this seemingly silly procedure. :(
Maybe, I'll switch to Wicd for a while, and see if that helps...
Memory leak that we expirianced is fixed in latest git. :D
"fix incorrect NR_FREE_PAGES accounting (appears like memory leak)"

Yeh, it could use more memory - one of the ways they got the price down to $250 was by simplifying the case - to add memory, remove keyboard, unplug and remove mother board, then have access to the memory and hard drive....not frustrated enough to try that yet.
