Re: [PATCH 0/1] Do a warm reboot instead of a cold reboot

How about resetting also twl4030 in case of reboot. E.g. remove all the scripts from the twl4030?

How about resetting also twl4030 in case of reboot. E.g. remove all the scripts from the twl4030? Even then we should be using warm reboot. The fact cold reboot works has been more luck then anything else. How hard is it to fix the module reset on boot ? And what does a OMAP watchdog reboot do ?
