A while back I upgraded to kernel 4.2 because of a wireless issue. That got fixed, but then 4.2 brought new problems of its own. First was the speaker popping on boot that’s specific to ThinkPad users. It showed up in early 4.2 kernels and was later patched. Which is useless to me now, since we’re on 4.3 anyway. So I bumped the kernel to 4.3 via Ubuntu’s Mainline PPA, and after that VMware started telling me it couldn’t find GCC 5.2. Side note: VMware China ran a 80% off promo for Singles’ Day, so I finally bought a legit license. And now you’re telling me it doesn’t work? Not acceptable.
