XO-4/Kernel/Testing

Final testing push default configuration:

• fs-update os26
• change-tag TS DEVL \ enable aggressive mode with repeated runs

Debugging configuration A (with wireless):

• log the output of the serial console,
• olpc-dev-kernel
• no_console_suspend

Debugging configuration B (without wireless):

• log the output of the serial console,
• olpc-dev-kernel
• no_console_suspend
• touch /runin/no-wireless
• echo blacklist mwifiex_sdio >> /etc/modprobe.d/olpc.conf

Testing is being tracked below by kernel git hash.

Kernel developers, put your new kernel in a new section here. Latest at top. Testers place links to reports indented under the kernel. Test reports should include Open Firmware and EC versions.
