Though I haven't yet publicly released any of my compiled Linux kernels to the public, I'm planning on retiring from leading-edge Raspberry Pi kernel development mostly due to the time consumption for cross-compiling (on my slow laptop), testing and debugging (on my Raspberry Pi). The Linux kernels I'm compiling is centric to Philippine region; that means technology that does not exist here (such as IPv6) or I'm not directly using (such as Wi-Fi) is removed prior to the compiling stages. Moreorless, I don't like having Linux Kernels emulating a Windows platform, where every piece of hardware known to mankind is either embedded in the kernel or categorized as a module.
The Trouble with 3.6.11+ kernels
All 3.6.11+ kernels have trouble with my China-made keyboards. I live in Philippines and nearly all of the computer accessories available, are made in China. When I'm using any of my keyboards (all made in China), I either get random key repeat (that won't stop unless I unplug the keyboard) or keyboard simply stops working. OpenELEC has this problem; most often, the keyboard functionality vanishes after a short period of time. Performing rpi-update currently promotes 3.6.11+ kernels, therefore my keyboards frequently malfunction, especially when driven through a hub.
Compiling the 3.6.11 kernel with my own patched USB drivers offers very little help. My only remedy is the eliminate the 3.6.11+ kernel from my Raspberry Pi.
Everything Works with 3.7.y kernels
When I first compiled 3.7.1 for my Raspberry Pi, I was surprised that everything work fine. And then, problems shown up for the kernel patches. Some of the kernel patches have forced me to rewrite my own patches; I just hate it when one patch negates a patch I've done! This morning, I finally compiled 3.7.9+ kernel for my Raspberry Pi.
Anyone else Compiling 3.7.y kernels for Raspberry Pi?
Actually, I think the correct question is, does anyone have 3.7.y kernels for download? I have written my own SD Card patching script, that replaces the kernel.img file on the root and replaces the modules directory in the /lib directory. (Can't be done on the Raspberry Pi!) After the patching script is completed, the SD Card is ready for running on the Raspberry Pi.
Prior to replacing the kernel, I run sudo SKIP_KERNEL=1 rpi-update on my Raspberry Pi to get the latest firmware installed.
